The a/tk gren launcher RPG-7 has been intro to provide the rif pl with a powerful and yet a lt a/tk wpn. It is shoulder-con, open tube and has no recoil. It can be easily man carried and taken anywhere, even when crawling and can be fired from any of the normal firing posns. The initial motive force is obtained by gas pressure produced by the burning of a propellant charge inside the rkt. Char 2. The main chars of the wpn are :- a. Mob. b. Lt wt. c. Accuracy. d. Pen. e. It can be used against all known type of A and B vehs with accuracy ensuring a first rd hit. f. It can be carried and fired by one man but needs a sec man to act as a rkt carrier and loader. 3. When the rkt is fired, gases and flames emerge from the convergent / divergent nozzle at high vel. Nos 1 and 2 must take precautions against this back blast, the danger zone of which extends up to 30 m from the rear of the launcher. 4. Char of HEAT Ammo a. HEAT rkt is capable of pen Hy armr up to 40.64 cm. b. HEAT rkt is capable of pen masonry up to 60.96 cm. c. Fuze used with gren is a piezo electric type. 5. Hit Probability at Various Rgs Rgs Hit Probability a. 300 m 100% b. 400 m 80% c. 500 m 30% Gen Description 6. The RPG-7 is a smooth bore, open end tube with two pistol grips, one for steady holding of launcher and the other with trigger and firing mechanism. The middle of the tube is enlarged and covered with wooden casing. The rear end has a bell mouth shape, one fixed mech sight and a telescope. The telescopic sight is fitted to the body on the left side of the tube. 7. The gren is loaded from the front of the launcher i.e. muzzle. The tail end goes into the body while the lead stays out. If the rkt does not encounter tgt within 4 to 6 sec of the firing the electric detonator starts operating, detonates primer of the self-destruction device that explodes the gren nose. 8.

The sight offers to measure the dist, speed and lead to be applied for a tgt, at a dist b/w 200 to 500 m. The sight is the same in all the char of PGO 7 (old sight), less the reticle pattern which offers the measurement of speed, dist and lead to be applied to engage the tgt. 2. Parts of Sight RS 1A Telescope a. Obj Lens. b. Rubber Eye Shield. c. Temp correction knob. d. Lateral adjustment screw. e. Prism. f. Forehead rest. g. Bty container. h. Mtg Bracket. i. Tumbler Switch. RESTD  9 RESTD 3. The Optical Sys of Telescopic sight a. Glass covers designed to protect the internal mech against pen by moisture and dust. b. Double lens obj to bring the image of the tgt to bear on the prism. c. Prism for the complete rotation of the image. d. Reticle holder with the reticle picture. e. Four lens eye piece, for seeing the image of the object. 4. The Reticle. There are three types of scale in the reticle pattern: - a. Network scale. b. Rg finding scale. c. Speed scale. 5. Network Scale. The network scale further comprises two scales i.e. rg scale and lead lines. a. Rg Scale. From top to down, is marked as 1, 2, 3, 4 and 5 graduated in 100 m. As the eff rg of RPG - 7 for a mov tgt is 300 m, therefore, the line 3 is prominent than other four lines. b. Lead Lines. At top cen of the reticle pattern the horizontal line is intersected by 17 x vertical line known as lead lines. The cen line contains (+) sign, the bore sight cross at the top, which is also known as line of fire. There are 8 x vertical lines on either side of the line of fire marked after interval of 4, 8, 12 and 16 each (from line of fire to out wards). Each vertical line represents 1 x lead for a tgt mov with the speed of 2 m/s. Lead will be applied in the same side of reticle pattern from where the tgt is approaching. 6. Rg Finding Scale. Below the rg scale, there are three diagonal scales to determine the rg of tgts having hts of 1.5, 2.3 and 3 m respectively. The rg finding scale consists of two lines each: - a. An upper dotted curved line with the fig 2, 4, 6, 8 and 10 written above it. b. A lower continuous straight line, with the figs 1.5, 2.3 and 3 written under each. c. The fig above the dotted curved lines represents the dist in 100 of m and fig under the straight line represents the ht of the tgt in m. 7. Speed Scale. At the bottom of reticle pattern, the horizontal line, marked as 0, 1, 2, 3, 4 and 5 graduated in 100 of m, is known as speed scale. For example, if a tgt is at 300 m, mov from left to right, coincide the tgt with fig 3, the no of lines the tgt crosses in one sec will be the speed of the tgt in m/s. RESTD  10 RESTD 8. The Ill set and Winter Ill Set. To asst the firer in laying the launcher at ni and in conds of adverse vis, the sight has an inbuilt ill set and an aux winter ill set. a. The Built-in ill Set. This consists of a bty box, a bulb fitted in the body and an on/off tumbler switch and connecting wire. The set uses one Mercury Oxide cell (type 20p2k). Once switched on, the bulb ill the reticle pattern in the sight. Winter Ill Set b. The Winter ill Set. This is an external set and consists of a tube for cells, a connecting wire and a cap. To use it, the cap of the winter ill set, which is connected with a cable, is put on the built-in ill set tube and the tube cap with the cell is put in and on the winter ill set. ON/OFF is indicated on Russian made sights and on Korean models as BK/BBik respectively. 9. Two lt filters are issued with each sight, an orange filter for use under poor lt conds or haze and a neutral or smoky filter for use in bright sun lt and glare. A rubber eye shield covers the eye piece to block unwanted lt and a rubber cover is provided for the obj lens. Both are secured to the body by rubber straps. 10. The Sight Carrier. This is a canvas pouch for the protection of the sight and is used to keep the sight along with the spare parts, tools and accessories. The spare parts, tools and accessories are kept in pouch pockets. The winter ill set and a flannel cloth for cleaning the outside and optical parts are kept in the outer pocket. The inner pocket contains: - a. Spare cells. b. Spare electric lamps. c. Two lt filters, orange and neutral. d. Combination wrench. e. Screwdriver. 11. Mech (Open) Sight of RPG-7. In the event of the telescopic sight being rendered unsvc or lost, an open or mech sight is fitted on to the launcher to enable the firer to cont his task unhampered. This sight is const on normal open sight sys and has foresight and rear sight. a. The Fore Sight. The open sight consists of a fore sight, which is housed, in a casing and a sight leaf placed in casing which carries a slide and a catch. Fore sight casing and casing of the sight leaf are trough shaped and spring loaded. The side walls of the casings are provided with holes for pins by which they are fixed to lugs on the barrel. Riveted to the casing bottom are locking springs which serve for locking the fore sight and sight leaf in the horizontal and the vertical firing posns. The sight has a tip which is aligned alongwith the "V" of rear sight into the tgt. (1) The sight has a tip which is aligned alongwith the “V” of rear sight into the tgt. (a) Launcher with Single Fore Sight Tip. A single, non-modifier fore sight tip is meant for use in temp below 4 °C. This tip does not have any indication on it. RESTD  11 RESTD (b) Launcher with Two Fore Sight Tips. This Launcher has two foresight tips, one fixed in the foresight and is meant for use in below 4°C and a modified foresight tip which is riveted in the foresight tip and raised or lowered by rotation. When the sight is raised a plus (+) sign is visible which is meant for firing in temp above 2°C whereas when the sight is Fore Sight fully lowered a minus (-) sign is vis. In the raised posn the plus (+) tip protrudes slightly above the built-in tip. b. The Rear Sight. The rear sight is also housed in a casing and is leaf spring loaded. One side of the sight has a slide to engage a loaded stud. The slide engages these when the latch is moved up or down. The sight has the fig 1,2,3,4 and 5 cut into it which indicates a rg of 100-500 m. The rear sight slide which moves up and down when Rear Sight the stud is pressed, has a window for seeing the rg and a “V” on top. With the raised sight the launcher is aimed like a normal rif i.e. “V” of the rear sight and the tip of the fore sight are brought in line with firer’s eye and the tgt. BORE SIGHTING OF RPG-7 (Ref: GSP – 1600) Intro 1. All wpns must be zeroed/bore sighted before firing to ensure that correct alignment of the barrel and the sight is obtained. The sighting eqpt of A tk gren launcher RPG-7 consists of the telescope sight and open mech sight. The telescopic sight can, whereas mech sight cannot be adjusted. 2. Prep of Launcher for Bore Sighting. The fol procedure should be adopted to prep the launcher for zeroing: - a. Put the launcher on a rest ensuring secure fastening and accurate laying. b. Stretch strings cross wise in the bore sighting gauge. c. Insert the bore sighting gauge into the barrel from the muzzle end. d. Fix the telescopic sight on the gren launcher. A. For Gren Launcher RPG – 7 with one foresight. e. Set the telescopic sight temp B. For Gren Launcher RPG – 7 with two foresights. correction knob in posn. All dist are in mm RESTD  12 RESTD f. Erect the sight leaf with slide and foresight in the firing posn with the sight slide at scale reading 3 i.e. for 300 m. 3. Method of Zeroing. Two methods for zeroing the RPG-7. a. The testing tgt method. b. The aiming pt method. 4. Sel of Zeroing Method. The method used will, however, depend upon the circumstances. The testing tgt method can be used indoors or under bad vis conditions eff, whereas an outdoor area and good vis are essential for the aiming pt method. The Testing Tgt Method 5. For testing the mech sight, explain and demonstrate as fol: - a. Place the testing tgt at a dist of 20 m from the rear sight slide. Ensure with the help of a plumb line, that testing tgt is upright. b. Lay the launcher on the testing tgt so that the cross wires of bore sight gauge are aligned with the cross lines in the cross of the testing tgt upper circle. c. Sight the launcher keeping the eye about 15 cm behind the rear sight. d. The tip of the (+) foresight i.e. for firing at temp above zero, when seen through the sight slide notch should not go beyond the limits of the upper white rectangle in the rectangle of the testing tgt. e. The tip of the (-) foresight i.e. for firing at temp below zero, when seen through the sight slide notch should not go beyond the limits of lower white rectangle of the testing tgt. f. Repeat the process at least four times. g. If the foresight tip is beyond the limits of the respective white rectangles of the testing tgt, in 50% of the total sighting, the launcher should be sent to the wksp for adjustment of the sights. A.

For testing the telescopic sight, sight the launcher through the telescopic sight and align the plus (+) sign, in the upper part of the sight picture with small cross lines in the testing tgt cross in the upper circle. If the plus (+) sign does not coincide with the hair line cross, adjust the telescopic sight as fol: - a. Adjustment of Error in Deflection. Unscrew cover a of the deflection screw, insert a screwdriver into the screw and turn the screw until the (+) sign in the sight moves in line with and covers the hair line cross in the testing tgt. b. Adjustments of Error in Elevation.

Check the sight for proper setting. The Aiming Pt Method 7. The second method for testing and zeroing the launcher is the Aiming Pt Method. To check the telescopic sight by this method the fol procedure is adopted: - a. Select an aiming pt at a dist of approx 300 m from the launcher. b. Lay the launcher through the bore sighting mechanism on to the aiming pt. c. Look through the telescopic sight, the sign (+) in the sight should cover the aiming pt in the same way as the bore sighting cross. If the telescopic sight is not properly aligned, correct the telescopic sight setting in the same way as explained in Para 5 a&b above. d. While checking the sighting eqpt, check the correctness of barrel on the aiming pt periodically to ensure correct zeroing. INTRO, FUNCS AND USE OF RED DOT SIGHT WITH RPG-7 Intro. 1. Initially RPG was provided with PGO-7 optical sight, however with adv in tech, new RS1A sight was inducted to replace the earlier sight. Even by using RS1A sight in fmns, firing results of RPG-7 were not encouraging and req improvement. 2. Detailed study was carried out at SI&T to analyze the underlying reasons of inconsistent results and it was found that the reticle of RS1A is very complex and firer often gets confused. A need was felt to enhance the hit probability of the wpn with some modification in sight. Decision was taken to test a sight which should be simple, user friendly and easy to handle. Hence, the idea of using Red Dot Sight was conceived. Description, Char and Specifications of Red Dot Sight. 3. Red Dot Sight is a non-magnifying reflector (or reflex) sight for firearms that gives the user an aiming pt in the form of a Red Dot, originally designed for SAs (G3A3 and SMG Chinese). RESTD  14 RESTD It has clear FOV and unlimited eye relief. The horizontal and vertical errors can be removed by using deflection and elev adjusting knobs respectively. Modification - Mtg of Red Dot Sight. 4. Mtg of Red Dot Sight on RPG-7 is made possible with slight modification in its picatinny rail. The details of modification are given below: - a. Total length of the rail mtg - 23.5 cm b. Length of picatinny rail - 20 cm c. Dist of front end of rail from barrel - 1 cm d. Dist of rear end of rail from barrel - Nil (should touch the barrel) e. No of projections on picatinny rail - 12 (The firer may adjust sight as per eye relief) Projections No space 1 cm 20 cm 23.5 cm Bore Sighting/ Zeroing. 5. To fire the RPG-7 at diff rgs, we may use the bore sighting/ zeroing procedures (testing tgt and aiming pt methods) as well as clicks method using Red Dot Sight. Details are as under: - a. Testing Tgt Method. (1) Bore sighting with Red Dot Sight can be done with a spec testing tgt called the “ALPHA GRID”. It consists of two crosses, upper for RPG-7 bore and lower for Red Dot Sight. The Red Dot cross should be 2 cm left of the bore sight cross to cater for the difference in lines of bore and sight. Vertical dist between both the crosses should be 26 inches at 25 Ms (for 300 Ms rg). The eff rg of the wpn will inc or dec as the vertical dist b/w two crosses is inc or dec on testing tgt. The std dists are as fol:- Rg (Ms) Dist b/w Crosses 100 8.7” 200 17.4” 300 26” 400 34.7” 500 43”.4 RESTD  15 RESTD ALPHA GRID Bore Sight Cross 2 cm 8.7” 100 Ms 17.4” 200 Ms 26” 300 Ms 34.7” 400 Ms 43.4” 500 Ms Red Dot Crosses (2) This method is useful when firer has ALPHA GRID sufficient time and resources aval to bore Bore Sight sight the wpn. Detailed procedure of Bore Cross Sighting with Red Dot Sight with Alpha Grid is as fol:- (a) Put the launcher on an aiming rest 26 Inch ensuring secure fastening and 2 cm accurate laying. (b) Stretch strings cross wise in the bore sight gauge. (c) Insert the bore sight gauge into the barrel from the muzzle end. Red Dot Cross RESTD  16 RESTD (d) Fix the Red Dot Sight on the RPG-7 using specific picatinny rail. (e) Place the Alpha Grid testing tgt at a dist of 25 Ms from the aiming rest on which the RPG-7 is placed. (f) The cross for Red Dot Sight will be 2 cms left of the bore sight cross. (g) Align the bore sight & Red Dot Sight with upper & lower crosses of Alpha Grid respectively. (h) While carrying out zeroing, eye relief from bell mouth should be 15 cms. (i) For testing the Red Dot Sight, align the bore sight cross with the plus sign on upper cross. Now check that the Red Dot is on the center of the lower cross. If the Red Dot does not coincide with the cross on lower circle, adjust the telescopic sight as fol:- i. Adjustment of Error in Deflection. Unscrew cover of the deflection screw, insert a screw driver into the screw and turn the screw until the Red Dot in the sight moves in line with the cross of lower circle. ii. Adjustment of Error in Elev. Unscrew cover of the Elev adjusting knob, insert screw driver into the screw and rotate the screw until the Red Dot is in line with the plus sign of lower circle of the Alpha Grid testing tgt. (j) RPG-7 is bore sighted and ready for fire at 300 Ms rg. (k) To fire on other rgs, the bore sighting will be done again ensuring the dists between bore sight and Red Dot crosses as mentioned a/m table. b. Aiming Pt Method. In this method, we sel an aiming pt at a req rg from the launcher. Aiming pt method req good vis as compared to the testing tgt method which can be eff used indoor or during low vis conditions. The complete procedure is mentioned below. (1) Sel an aiming pt at a req rg from the launcher. (2) Lay the launcher through the bore sighting mech on the aiming pt. (3) Look through the Red Dot Sight, the Red Dot should be placed on the aiming pt in the same way as the bore sight cross. If the Red Dot is not at the same spot, apply corrns as per the procedure a/m in para (2)(i) of testing tgt method. (4) While checking the Red Dot, check the correctness of barrel on the aiming pt periodically to ensure correct zeroing. c. Clicks Method Using Red Dot Sight. Once the wpn is bore sighted/ zeroed at 300 Ms using any of the a/m procedure, it can also be adjusted for any other rg by mov clicks of Red Dot Sight. This method is helpful once any opportunity tgt appears in front of the firer or when the ideal conds or resources are not aval. In this procedure, the firer has to apply 36 clicks with elev adjusting knob for every 100 Ms change of rg. This procedure has the advs over a/m bore sighting procedures due to following reasons: - (1) The firer can imed switch over to any rg without delay. (2) The firer can eff engage the tgt at intmed rgs (other than specific 100, 200 & 300 Ms etc). RESTD  17 RESTD 6. Ni firing cap of RPG-7 can also be achieved by mtg AN/PVS-14A (monocular) or AN/PVS 7D on the forehead/ helmet of the firer due to which tgt can be easily seen through the sight and fire is successfully conducted with Red Dot Sight already zeroed during day time. This does not need any calibration/ bore sighting again. LOADING/UNLOADING OF RPG-7 (Ref : GSP – 1600) Intro 1. Being an eff short rg A Tk wpn held with Pl, its use, func and loading / unloading is very imp aspect which every offr should know. There may be occasions / incidents of misfire, which req a deliberate procedure of unloading and disposing off of the misfired rkt. 2. Procedure of Preparing the Gren for Firing / Loading. No 2 examines the gren, connects the cart and removes the safety cap from the fuze. He makes sure that the rds, with external signs of damage, to fuze or body, gren or booster, are not fired, and then prepares the gren for firing in the fol seq:- a. Opens the plastic/paper case and removes the cart from it. b. Unscrews the safety lock with gas ket from the tail of the rkt booster. c. Screws the cart on to the lug at the bottom of the rkt booster until the end face of the cross piece projecting beyond the base surface joins the bottom. NOTE. DO NOT APPLY EXCESSIVE FORCE WHEN SCREWING THE CART. RDS WITH INCOMPLETELY SCREWED CART SHOULD NOT BE USED FOR FIRING. 3. Now explain and demonstrate the duties of no 1 and No 2:- a. Duties of No 1. The safety cap from the rkt by pulling out the safety pin by the tape and removes the cap. He will then move the safety lock to “SAFE” and makes sure the cocking piece is up, taps No 2 on the shoulder and orders launcher body to hold it steady and keeps the launcher head in the dir of the tgt. b. Duties of No 2. No 2 on receiving the comd “Load” from No 1 acts as fol:- (1) Repeats the comd “Load”. (2) Picks up the gren in his left hand, the head of the gren pointing towards the tgt. (3) Inserts the rd into the muzzle end of the launcher tail first and pushes it firmly in, till the gren retainer stud fully enters the recess on the barrel muzzle end. (4) If the rd is tight or if the gren retainer does not sit in the recess in the muzzle end, the rd is turned ctr clockwise and pushed in. RESTD  18 RESTD (5) Taps No 1 on the shoulder and calls “UP”. c. No 1 mov his right hand to the grip of firing & trigger mech, and prep to fire. 4. Unloading. Explain and demonstrate the duties of No 1, using a student as No 1. Instr should be in posn as No 2:- a. Action of No 1. In case the gren is not fired and has to be removed from the launcher, No 1 makes the launcher safe, Taps No 2 on the shoulder and calls “Unload” placing his rt hand on the launcher. b. Action of No 2. No 2, repeats the comd of “Unload” and wdrs the rd from the launcher muzzle. Unscrews the cart form the bottom of the gren, places the cart in the case, and screws the safety lock with gasket on to the bottom of the gren. NOTE. IF THE COCKING PIECE HAS BEEN ARMED NO 1 HOLDS THE COCKING PIECE WITH HIS THUMB PRESSES THE TRIGGER AND SLOWLY RELEASES THE COCKING PIECE. TRIGGER OP AND MISFIRE DRILL RPG-7 (Ref : GSP – 1600) 1. Func of Firing and Trigger Mech. Before the cocking piece is armed, the parts of the mech occupy the fol posn:- a. The cocking piece is held in posn by the pressure of the two lugs of the cocking rod. b. The cocking piece safety lug is engaged by the sear. c. One end of the sear rests against the cocking piece safety lug and simultaneously presses Trigger Mech RPG-7 against the upper tooth of the trigger. 2. When arming the cocking piece by mov it downward, the part of the trigger mechanism mov and act as fol:- a. Cocking piece pressed by the thumb of the hand, rotates around its pin and presses against the big lug of the plunger rod. b. The sear moves upward and engages the cocking nose, thereby arming the cocking piece. c. The trigger occupies the fwd most posn due to the mov of the sear. 3. When the trigger is pressed the parts of the firing and trigger mech func as fol:- a. The upper tooth of the trigger, turning on its pin, lifts the sear. b. The sear disengages from the cocking piece. c. The plunger reacting under the pressure of its spring mov upwards presses against the cocking piece with its big lug and turns rd, on its pivot. d. On reaching the posn occupied before arming, cocking piece cont to mov upwards under the force of inertia and not under the pressure of cocking spring. e. While doing so the cocking piece strikes the firing pin, which detonates the gren. The upward mov of cocking piece is stopped by firing pin. f. As the cocking piece mov upwards under its own mov, its shorter arm goes down, presses against the smaller lug of the plunger and makes the plunger rod move slightly down there by slowing the further mov of the cocking piece. g. After the force of inertia has been dispelled, the plunger rod, actuated by the pressure of the plunger spring rises with its smaller lug, the short arm of the cocking RESTD  19 RESTD piece and thus turns it on its pin in the opposite dir to lower its serrated sec till contact is made with the bigger lug of the plunger. h. Now, tooth of sear as before arming, rests on the horizontal surface of the cocking piece safety lug. i. One complete mov from cocking to firing is thus completed. Misfire 4. If the rd does not fire after pressing the trigger then fol action is taken:- a. Action No 1 (1) Arm the cocking piece again, take the aim and fire. (2) If no fire occurs, then take his finger from the trigger gd. Put the safety lock on safe. Ensure that the cocking piece is up. (3) Put his hand on the shoulder of No 2 and call ‘MISFIRE’. b. Action No 2 (1) Repeat comd of ‘MISFIRE’. (2) Check whether the rd has been completely rimmed into the launcher bore. Fits the rd until the retainer bears against the muzzle face recess. (3) Call ‘UP’. 5. If the rd still does not fire then fol action is taken:- a. Action No 1 (1) Repeat drill as per para 6 a. (2) Give order to no 2 “Misfire Unload”. b. Action No 2 (1) Repeat comd of ‘MISFIRE’. (2) Take out the rd from the barrel and check fol:- (a) Check ignition primer if defective. (b) Check the firing pin if worn out. c. If the primer has been hit, load another rd. d. If firing pin is worn out, change firing pin. e. If the firing pin does not strike against primer with force owing to contamination of lubricant on firing and trigger mech or if the barrel is dirty. Clean the firing and trigger mech or the barrel and reload the same rd. Change lubricant if req. 6. If the rd is still not fired, then No 1 gives fol orders to No 2:- a. Order to No 2 ‘MISFIRE UNLOAD’. b. Strip firing pin assy and if the firing pin is broken change it. c. If the firing pin is not broken then strip firing and trigger mechanism cover plate and check trigger assy for some broken part or any part that has shifted from its original place, if req take launcher to the wksp.

Five different types of munitions can be fired from ALCOTAN RL-100 (M2). The effects of their warheads char munition types. Each type of munition is electronically tagged so that the FCU can recognize them. a. ALCOTAN-AT A tk. b. ALCOTAN-BIV dual purpose (anti-armr and fragmentation). c. ALCOTAN-ABK anti-bunker. d. ALCOTAN-EJ prac. e. TR-ALC (M2) sub calibre trainer (9 mm). 2. Each munition consists of: a. Container Launcher. b. Launch Motor. c. Projectile. 3. Container Launcher. The Container Launcher can be disposed after firing. Main components of the Container-Launcher are fol:- a. Container Launcher Tube. It is made of fiber reinforced resin and has been designed to with stand the internal pressures generated during the launching ph as well as the external environmental challenges. b. FCU Interface. It consists of:- (1) Connection Block. To receive activation sig for ignition of the Launch motor. (2) Coupling Guide. Mech adapter that keeps the FCU fixed and bore- sighted with the Container Launcher. (3) Protective Covers. It close the Container Launcher in order to protect the Launch Motor and the projectile inside. The front protective c over must be removed before firing while the rear end cover is permanently att to the Container Launcher tube. (4) Carrying Strap and Shoulder Pad. To facilitate carrying and handling of the wpn sys. 4. Launch Motor. It provides:- a. High initial vel of the projectile. b. Min recoil lvl. c. Once the tracking and firing cycle has been properly carried out, Launch Motor functioning seq is as fol:- (1) On pressing the Fire push-button, the propellant inside the combustion chamber is electrically initiated. (2) The pressure generated pushes both the projectile and the Counter-Mass, which are accelerated in opposite dirs, keeping equal momentum. (3) The projectile leaves the Container Launcher fwd and the counter-mass pushes the Container Launcher backward being fragmented and dispersed in small particles. 5. Projectile. The projectile consists of:- a. Warhead. b. Fuzing sys. c. Sustainer motor. d. Stabilizer. RESTD  28 RESTD 6. Warhead. The warhead is the distinguishing element of different munitions. Types of warhead used with this wpn sys are fol:- Warhead Description ATA tk Specifically designed to defeat main battle tks (MBTs) protected with expl reactive armr (ERA). It consists of two shaped charges: the precursor warhead to defeat the ERA protection, and the main warhead to defeat main armr. BIV dual purpose (anti It is a shaped charge warhead with fragmentation case. The armr and design is optimized to defeat lt armr vehs and accompanying fragmentation) tps. ABK anti-bunker (1) It is a double charge warhead designed to beat tps or material protected by bunkers, buildingsand non- permanent fortifications. (2) The precursor warhead is a shaped charge that perforates the wall of the tgt. The secwarhead (fragmentation charge) passes through the hole made by the precursor charge and detonates about 2 to 3 m inside the bunker, producing the same effects as a powerful hand gren. (3) Being a shaped charge, the precursor warhead is also eff against lt armd vehs. EJ inert It is an inert warhead, having the same external shape, wt and aerodynamic char as the BIV warhead. EJ warhead is used for prac. 7. Fuze. Depending on the type of warhead, ALCOTAN-100 (M2) munition uses a different fuze that match the specific reqs of warhead. Warhead Description AT (1) Fuzing sys consists of two independent electro-mech fuzes that once activated by the FCU, are completely autonomous and generate the electric energy req to initiate the detonator on impact on the tgt. (2) Electronics con the time delay between the initiation of the precursor warhead and the initiation of the main warhead in order to assure the best performance against ERA protected tgts. (3) Fuzes are provided with self-neut feature that neut the rd after specific time of flt. BIV It incorporates one impact, completely autonomous fuze. ABK The fuzing sys consists of two independent fuzes (same as in AT). EJ It does not in corporate any fuze. 8. Sustainer Motor. The ALCOTAN-100 (M2) projectiles have a sustainer motor that compensates the aerodynamic drag. The sustainer motor is a rkt motor that ops during the flt up to 600 m rg. At this rg, A tk wpns require a relatively high initial vel. Hence, accuracy of the projectile will be higher if this vel is kept more constant. The sustainer motor of the ALCOTAN-100 (M2) projectiles keep the projectile vel almost constant, thus increasing the single shot hit probability. RESTD  29 RESTD 9. Stabilizer. The stabilizer installed in the rear of sustainer motor assures the stable flt of the projectile. It consists of six fins that are opened imed after the projectile lves the Container Launcher. 10.

RESTD  33 RESTD ALCOTAN MODE: OP AND FUNCTIONING 1. "ALCOTAN MODE" is the mode of op for firing the munition. 2. Prep for firing has fol steps:- Remove the seal tape, turn the front cover counter- clockwise and remove the munition’s front cover. Remove the protection from the munition coupling guide. Take the FCU out of the carrying bag. Insert the bty by sliding it on the guide till the time it is fixed. Hold the FCU with the locking lever. RESTD  34 RESTD Slide the coupling guide of the FCU on to the munition, andlock it by pushing and turning the locking lever clockwise upto the pt FCU gets fixed. Remove the obj lens protective cover. Adopt the firing posn:- (1) Left hand on the FCU, on the Tracking push-button. (2) Right hand holding either the Container-Launcher or the FCU. (3) Whenever possible, fire from aspposn. (4) To fire from a non- sp posn, one of fol two posns are recommended:- (a) Sitting posn: Lean fwd and place the upper arms on yourknees or place yourelbows on your thighs. (b) Kneeling posn: Place the right elbow on the right knee. Use the carrying strip to hold the wpn sys. When looking through the eye piece if the backgr image and msgs are not focused, rotate the dioptre adjustment ring. RESTD  35 RESTD Lift the Fire push-button cover, FCU will turn on. The type of munition is automatically detected, and the temp of munition is automaticallymeasured. Msgs identifying the type of munition can be: "ALCOTAN-AT" - Tandem A tk "ALCOTAN-BIV" - Dual purpose (anti-armr / fragmentation) "ALCOTAN-ABK" - Anti-bunker "ALCOTAN-EJ" - Prac "ALCOTAN-TR" - TR-ALC (M2) trainer subcalibre trainer. Aim at the tgt and push the tracking push-button, the tracking and firing cycle is thus started. Tracking push- button shall remain pushed during the whole firing cycle. The FCU determines the rg to the tgt and shows the measured value on the display for ltd time. While pushing the tracking push button, tr the tgt until the FCU calculates the Future Aiming Pt that is shown as a blinking crosshair. Future Aiming Pt is determined considering rg, tgt mov (i.e sty, transverse mov as well as vehs mov directly towards or away from the gnr) and the appropriate ballistic tables. Move the wpn to aim the tgt with the blinking crosshair (Future Aiming Pt). Tracking push-button shall remain pushed during the whole firing cycle. RESTD  36 RESTD Fire the wpn by pushing the Fire push button (red coloured). The FCU estimates a valid time for calculations. If this valid time is elapsed before firing, the msg "OUT OF TIME" will appear on the display. Firing cycle is over once the rd is fired. Release the Fire push-button. The Firing Con Unit turns off. 3. Firing Cancellation Release the tracking push button. The msg "CANCELLED FIRING" will be displayed. 4. On completion of firing, disassemble the wpn sys in the reverse order of assembling. RESTD  37 RESTD 5. Msgs During the Tracking and Firing Cycle. The fol msgs could appear during the tracking and firing cycle:- Msg Display Cause Laser rg finder does RANGE FINDER ERROR not work properly. The msg “SIGHT” and cbt sight are seq shown on the display. SENSOR ERROR Triaxial sensor does not work properly. Msg “QUICK FIRING” and a blinking crosshair, which is corrected for rg but without correction for transverse mov, will appearon the display. The gnr can still fire the munition with an adequate elevation correction. MUNITION ERROR Either there is no munition connected to the FCU or the munition is not detected. The munition either is not connected correctly or is damaged. Check connection (locking lever) and restart the firing cycle. RESTD  38 RESTD Msg Display Cause TEMP ERROR Temp of the munition propellant is out of the safety temp rg for firing. The FCU cancels firing but it can be used for rg finding (Measurement Mode). RANGE ERROR Rg measured by the rg finder is less than 100 m. ANGLE ERROR Posn angles of the FCU are out of the permitted rg. Transverse mov of the tgt LATERAL ERROR is out of the permitted rg. The FCU estimates a OUT OF TIME valid time for calculations. If this valid time is over before firing, the msg "OUT OF TIME" will appear on the display. RESTD  39 RESTD Release the tracking push-button; the msg "CANCELLED FIRING" will be displayed and the firing cycle will start again. If the tracking push-button is not released and the trigger push button is pushed, the msg "TRIGGER ERROR" will appear. The FCU is req to be turned off inorder to start a new firing cycle. 6. Use of Cbt Sight. The FCU shows the cbt sight to allow the gnr to aim when either “RANGE FINDER ERROR” or “RANGE ERROR” msgs have appeared. The cbt sight shows rg markings from 0 m to the max firing rg of the munition connected to the FCU, in steps of 100 m. The digits identify the rg in steps of 200 m. The stadimetric curves will help to set the wpn at the elevation angle adequate to the rg of the tgt. They are designed for a tgt of 6.3 m long and 3 m wide (med size tk). To identify the desired elevation angle, fix the tgt in between the outer curves of the sight. If the tgt is coming from front, fix it in between vertical central line and the corresponding stadimetric curve and after maintaining the elevation angle, estimate correct dir to t h e centre o f the tgt. On the cbt sight there are markings for transverse mov tgts, for rgs of 200 m, 400 m and 600 m, mov with vel of 20 km / h and 40 km / h.Tgt vel will be estimated by the gnr. The illustration shows a tgt at a rg of 400 m, traversing left to right at 40 km / h, correctly aimed. RESTD  40 RESTD 7. Other Cons a. Ni Vision.

Gnr can be guided by the Instr and can make corrections. 4. TR-ALC (M2) Sub Cal Trainer. TR-ALC (M2) sub cal trainer is designed by Instalaza, to provide an eco and eff trg for ALCOTAN-100 (M2) wpn sys gnrs. The TR-ALC (M2) presents the same wt, external shape and the interfaces of the tac ALCOTAN-100 (M2) munitions. It uses 9 mm cart and gives the gnr feel of the back blast as well. Tracer bullet with rear blast charge and can be fired on 900 m rg. 5. Main Component of TR-ALC (M2) Sub Cal Trainer a. Sub Cal Barrel Insert Assy. It consists of a 9 mm barrel, breech bolt, electrical contacts, and sp. b. Container- Launcher Tube. It consists of the launch tube and the interface with the VOSEL (M2). c. CAR.TR-ALC Ammo. The CAR.TR-ALC is the ammo used with the TR-ALC (M2). It has been uniquely designed for the TR-ALC (M2), and its design is patent protected. Main elements of the CAR.TR-ALC are the fol:- (1) Tracer bullet cart. (2) Blast charge. (3) Electrical contacts circuit. RESTD  45 RESTD (4) Electric igniter. (5) Firing pin. (6) Protective cap protects the tracer bullet cart. 6. Procedure of Using SAARA Ser Procedure Display a. Lift the cover of the fire push-button. FCU will turn on, type of munition is detected and the temp of the munition is measured. b. Msgs "ALCOTAN MODE", ident of the munition on use and aiming cross hair will appear seq on the display. c. Push the Sty Tgt push-button (marked with a house symbol). Sty tgt option is activated. d. The msg "STATIC TGT" and a steady aiming cross hair are seq shown on the display. When the FCU is turned on, the sty tgt option is always deactivated. It should always be turned on. e. Aim at the tgt and push the tracking push button, the tracking and firing cycle is thus started. Tracking push button should remain pushed for complete firing cycle. f. FCU determines the rg o f the tgt and shows the measured value on the display for a short time. RESTD  46 RESTD Ser Procedure Display g. When the measured rg is less than 600 m and the area tgt munition is connected to the FCU, the msg "EXTENDED RANGE" is shown on the display. When the measured rg exceeds the max rg of the munition connected to the FCU, the msg "RANGE ERROR" is shown on the display. h. Future Aiming Pt is determined considering rg and the appropriate ballistic tables. i. Mov the wpn to aim the tgt with the blinking Cross hair (Future Aiming Pt). Tracking push-button shall remain pushed for the whole firing cycle. j. Fire the wpn by pushing the fire push button (red coloured). In the Sty Tgt Mode, there is no time ltd for tracking. k. Once rd is fired, the firing cycle is completed. l. Release the Fire push-button and bring the cover lid down. Firing Con Unit turns off. SAFETY PROCEDURES 1. Precautionary Measures a. Damaged FCU or munition should not be used. b. FCU showing abnormal behaviour (in correct functioning seqs, wrong or incomplete msgs, etc) or showing complete failure when Auto-Test is performed, should not be used. c. If the image intensifier (II) tube is out of order, it is not possible to use the FCU under low brightness conditions. However, it can be used in day lt. d. FCU could show msgs indicating it is not working in optimum conditions. These conditions will never jeopardize the op safety. These msgs include:- Msg Description HALF BTY The FCU can still be used for ltd time. So, gnr should be prepared, RESTD  47 RESTD Msg Description and replace the bty when possible. LOW BTY The bty in the FCU is almost exhausted. It must be imed replaced, and must be recharged as soon as possible. RANGE FCU can not measure the rg of the tgt, so it can not calculate the FINDER future aiming pt. However, it can still fire munition using the cbt ERROR sight. The FCU can also be used as ni vision device. SENSOR FCU can not determine the transverse vel of a mov tgt. ERROR FCU can still be used as obsn / surv or as rg finder device under day lt as well as at ni. 2. Misfire. On pressing the Fire push-button, if the rd is not fired, fol steps should be carried out ensuring the wpn sys is pointing towards the tgt and the rear danger zone (back blast area) is clear:- a. Release both the fire push-button and the tracking push-button. b. Close the cover of the Fire push-button; FCU will be turned off. c. Repeat the whole firing cycle. d. In case the rd is still not fired, perform fol steps:- (1) Release the Firing and the tracking push-buttons. (2) Close the cover of the fire push-button; the FCU is then turned off. (3) Wait for about 30 sec, while keeping the wpn sys in firing posn and aimed towards the tgt, then place the wpn sys on the gr pointing towards the tgt. (4) Remove the FCU from the munition. (5) Perform Auto-Test of the FCU to check whether the problem is with the FCU. If so, send the FCU for maint. STORAGE AND PACKAGING 1. Munition Storage. No special care is needed. However, if possible, munitions should be stored in their original packing. 2. VOSEL (M2) Fire Con Unit Storage. Fol storage conditions be ensured:- a. Always store the FCU inside the carrying bag and if possible, inside the hard case. b. Never exceed the storage temp limits shown in the hard case. c. Before packing FCU inside the carrying bag and subsequently placing the carryin
