Infantry Communication - Basic

Within a Fireteam it is important that personnel are able to communicate clearly and effectively. Most communication in a Fireteam is verbal communication and does not rely on a radio.


Fireteam members should only use the radio when separated from the team leader or when transmitting information that is time critical to the entire squad.

95% of Fireteam communication is verbal and does not require radio use

In general the squad network should be kept clear so that Team Leaders can talk to Section Leaders

Communication within the Section is done within discord, with all eight men being issued personal role radio systems to communicate within the group. This communication is constant and does not have to be serious all the time, mainly used for coordinating and getting the section to its work. The Section IC and 2IC needs to be clearly established so orders can be issued.

Contact Report:
  1. (Their Callsign) this is (Your Callsign) Contact Report, over.
  2. (Their Callsign) this is (Your Callsign) send it, over.
  3. (Their Callsign) this is (Your callsign)…..
  4. (Strength of enemy)

  10. How copy?

Infantry Communications - Advanced

There are many formats for messages - the standards for which are laid out on this page. This page starts with the more basic information - such as the NATO phonetic alphabet - and eventually develops into more complex multi transmission messages.

Tactical Reports and Requests will be covered in the next chapters.

The NATO Phonetic Alphabet

The NATO Phoentic Alphabet is used when an alphanumeric character needs to be expressed over the network.


Section-to-Section Communication

To communicate with a section, The Section IC and 2IC are assigned codenames as their sections name and fireteam. For example, The IC of Bravo One would be Bravo One Charlie as a callsign and 2IC Bravo One Delta.

The way to communicate is to hail the section over radio by doing so:
  1. (Their Callsign) this is (Your Callsign), message, over.
  2. (Their Callsign) this is (Your Callsign), send it, over.
  3. (Their Callsign), (Your message), over.
  4. (Their Callsign), (Acknowledgement), over.
  5. (Your Callsign) out.
  6. (Their Callsign) this is (Your Callsign), interrogative, over.
  7. (Their Callsign) this is (Your Callsign), send it, over.
  8. (Their Callsign), (Your message), over.
  9. (Their Callsign), (Acknowledgement), over.
  10. (Your Callsign) out.
