Study Notes

Six Elements of Call for Fire

Identification: Call sign of the observer and the unit being contacted.
Warning Order: Specifies mission type; includes Adjust Fire, Fire for Effect, Immediate Supp/Smk, and Suppression.
Target Location: Methods include Grid (MGRS), Polar (Direction & Distance), and Shift from a known point.
Target Description: Includes Size/Element, Nomenclature/Nature, Activity, and Protection (acronym: SNAP).
Method of Engagement: Specifies parameters such as Danger Close (600m), ammunition type (High Explosive, Point Detonation), and trajectory (Low/High Angle).
Method of Fire and Control: Includes options like When Ready, At my Command, and Time on Target.

Target Location Methods

Grid Method: Uses a minimum of 6 digits for MGRS; can send up to 10 digits, along with altitude.
Polar Method: Involves specifying direction (nearest 10 mils), distance (nearest 100 meters), and elevation change (noted in increments).

Deviation Correction

Calculated using OT Factor multiplied by spotting (OT x Spotting = Deviation Correction).
The minimum deviation correction that can be sent is 30 meters.

Observer Target (OT) Factor

Determined by dividing the distance from observer to target by 1000; express as a whole number or decimal depending on distance.
Example: For a distance of 2700 meters, the OT Factor is 3.

Transmissions

Message to Observer (MTO) includes: Call sign of unit(s), changes to Call for Fire, number of rounds per tube, and target number.
Terms used: "SHOT" indicates each round fired during adjustment; "SPLASH" informs that a round is five seconds from detonation; "ROUND COMPLETE" signals the end of fire for effect phase.

Polar Missions

Observer must send their location to the Fire Direction Control (FDC) before executing a Polar Call for Fire.
Second transmission should include direction (nearest 10 mils) and distance (nearest 100 meters), alongside changes in elevation if necessary.

Successive Bracketing

A technique used to establish a bracket where one round lands over and another short of the target, especially beneficial for inexperienced observers.

End of Mission

Concludes the call for fire, including refining corrections, recording, and ensuring surveillance of the situation.

Danger Close

For artillery and mortars, Danger Close is defined as 600 meters or less from friendly forces.

Standard Practices

Standard trajectory for artillery is Low Angle.
Standard method of target location in a CFF is Grid, when not specified otherwise.
Always send direction in increments of 10 mils and distance in increments of 100 meters.

Additional Notes

Ensure to correct deviations promptly. If correction is less than 30 meters, it does not require a correction.
In case of polar calls, always specify elevation changes if they exceed 35 meters.
Communication is critical; clarity in each transmission strengthens operational effectiveness.
