Study Notes
Introduction to Line Laying
- Line communication is crucial for effective military operations, especially within the Armoured Corps.
- Ensures secure communication during defense and operations, particularly in harbor areas.
- Familiarity with line equipment is essential for quick and successful line laying.
Sequence Overview
- Part-1: General points, terminologies, advantages/disadvantages, characteristics of cables.
- Part-2: Types of cables, reels, and major parts involved in line laying.
Line Laying Techniques
General Points
- Static communication is more comfortable than radio for operators.
- Security and maintenance of lines post-laying are collective responsibilities.
- Line communication is primarily used in exercises and defense operations.
Terminologies
- LB Operation: Utilizes own batteries for telephone and exchange.
- CB Operation: Involves using exchange's battery only.
- Local Circuit: Utilizes one exchange.
- Trunk Circuit: Connects multiple exchanges.
- Point to Point Circuit: Direct connection between two telephone sets without an exchange.
Advantages and Disadvantages
- Advantages:
- Immediate communication once wires are laid.
- Secure against weather conditions.
- Allows simultaneous messaging.
- Disadvantages:
- Difficult initial setup and manpower-intensive.
- Hard to replace lines and maintain during movement.
Characteristics of Cables
- Cables should be strong, lightweight, low resistance, well-insulated, and flexible.
- Factors influencing line communication include cable type, laying method, and power supply.
Types of Cables
- Assault Cable: Single copper wire, non-recoverable post-laying, can be laid using aircraft.
- Wire WD III: Manufactured in the USA, consists of copper and steel, weight 48 lbs per mile, withstands high pressure.
- Wire D-8: Poor insulation, similar structure to WD III.
- Wire W-3 and Others: Varied insulation durability, made in Pakistan, composition and quality may differ.
Reels for Wire Management
- DR-5: Holds up to 2.5 miles of wire, made of iron.
- Wire Dispenser MX-1302 A/B: Canvas-made, supports rapid wire laying at high speeds.
- RL-31: Versatile reel for vehicle or ground mounting, capable of holding multiple wires and equipped with braking mechanisms.
Line Laying Techniques
Types of Line Constructions
- Ground Cable: Cost-effective for short deployments, requires minimal digging.
- Underground Cable: Essential for heavy traffic areas, requires careful burial techniques.
- Aerial Cable: Best for overhead installations, ensuring adequate clearance from the ground.
Crossings
- Overhead Crossing: Commonly used near command posts and during troop movements.
- Underground Crossing: Ideal for non-metallic surfaces, involves trenching methods.
- Specialized Crossings: Requires caution for railways and water bodies, ensuring proper insulation and labeling.
Essential Considerations for Line Laying
- Assess whether the line is temporary or permanent.
- Conduct intelligence reconnaissance (recce) to gather vital information on the environment.
- Maintain speed and protection during line laying to facilitate quick adjustments and easy maintenance.
Labeling and Maintenance
Labels
- Important for identifying specific line sections and ensuring operational clarity.
- Use consistent non-matching letters for formations.
Maintenance
- Conduct daily inspections and keep accurate records of line usage.
- Maintenance personnel should be skilled and equipped with necessary materials for repairs.
