Signal Communication Overview

Signal Communication

• Signal communication conveys information between individuals or locations, excluding direct communication.
• Means of communication are mediums for message transfer.
• Agencies of communication provide personnel and equipment for signal communication.
• Tactical radio sets are the primary communication means for tactical units, used for command and fire control.
• Two main types of signal communication are physical and telecommunication.

Physical Communication

• Messenger: The oldest, relatively secure method.
  • Advantages: Most secure, transmits bulk items, doesn't rely on electricity, no complex setup needed.
  • Disadvantages: Slow transmission, no direct contact, weather dependent.
• Trained animals: Utilize animals' abilities to traverse difficult terrain.
• Mail: Considered physical communication; used within lower military echelons.
• Wire: Used in all military units, employing field wires and cables.
  • Advantages: Person-to-person contact, capable of operating with breaks, relatively secure.
  • Disadvantages: Time-consuming installation, susceptibility to sabotage and destruction, terrain obstacles.

Telecommunication

• Telegraph: Long-distance communication.
• Radio: Fast, frequently used for command, highly flexible and mobile.
  • Advantages: Faster than wire, flexible and portable, integrates with wire facilities.
  • Disadvantages: Equipment malfunctions, atmospheric conditions, interference, least secure.
• Visual signals: Control small-unit actions.
• Sound signals: Primarily for alarms, used for short distances (limited by range).
  • Advantages: Transmits short messages, suitable for short distances, not location-dependent.
  • Disadvantages: Easily intercepted, range limited, effected by battle noise.

Fundamentals of Tactical Radio Communication

• Radio Net: Stations operating on the same frequency.
• Call sign: Pronounceable words identifying stations within a network.
• Collective call sign: Used for multiple (but not all) stations within a network.
• Net call sign: Identifies all stations in the network.
• Call: Establishes communications.
  • Pro words: Pronounceable words to aid transmission.
  • Over: Transmission ends, waiting for a response.
  • Roger: Confirmation of message reception.
  • Out: Transmission ends, no response needed.
  • Wilco: Compliance to instructions.
  • Query: Request for clarification.
  • Lima Charlie: Received loud and clear.
  • Say again: Request for retransmission.
  • Request net with ...: Example of requesting connection with specific personnel.
  • Wait one: Request for delay in communication.
  • Read back: Repeat/copy transmitted messages.
  • Radio silence: Cease transmission but listen.
  • Break-break: Stop conversation to allow urgent transmissions.

Phonetic Alphabet

• Used to identify letters in spoken communication, avoiding confusion.
  • Includes letters A through Z with corresponding pronounceable words.

Numerical Pronunciation

• Standard pronunciation of numbers 0-9.

Morse Code

• Represents letters and numbers using dots and dashes.
  • Includes example representations of each letter and number.

Intelligence

• Intelligence: Collection, evaluation, and analysis of information.
• Counterintelligence: Actions to protect information.
• Intelligence cycle: Repeating stages of intelligence gathering.

Phases of the Intelligence Cycle

• Planning: Critical phase for production.
• Collection: Gathering information.
• Processing: Analyzing the collected data.
• Dissemination: Sharing information.

Additional Intelligence Considerations

• Enemy capabilities: Identifying enemy strengths and weaknesses.
• Weather/terrain: Weather and terrain information's effect on operations.
• Order of battle: Enemy unit information needed for long-term planning.
• Preventing surprise: Avoiding tactical surprises and gathering intelligence from adjacent units assigned collection missions.
• Essential elements of information (EEIS): High-priority information for commanders.
• Other intelligence requirements: Commander's needs that aren't top priority.
• Collection worksheets: Means for collecting information (written or oral).
