Purpose

  1. The aim of this SOP is to standardise the radio telephone (RATEL) procedures for the 39BN.
  2. This SOP should be used as a general reference by users and operators of radio equipment in the tactical environment; in particular, signalers and commanders at all levels.

Scope

Radios, Radio Setup and Ratel Protocol, applies to the 39th Battalion AIF Arma 3 Clan. As radio/telephone (RATEL) communication forms the backbone of clan communication during games of any size and scope, this procedure is essential to all personnel regardless of rank, position or specialisation.

Prerequisites

Personnel will require basic knowledge in:

  • Install of the Advanced Combat Radio Environment (ACRE) modification
  • Understanding of the relationship between the Teamspeak client and ACRE mod
  • Arma3 in-game inventory manipulation in order to equip any ACRE radio for use.

Responsibilities

Procedure

This procedure is to be used to when operating the in-game Radios.

  1. Speech. Speech will be more easily understood if the following rules are obeyed:
    1. RHYTHM – Keep a natural rhythm. Divide messages into sensible phrases.
    2. SPEED – Slightly slower than normal conversation.
    3. VOLUME – As for normal conversation. Shouting causes modulation, which results in distorted signal.
    4. PITCH – The voice should be pitched higher than usual.
  2. Discipline. Good discipline is essential to the efficiency of radio nets. Radio discipline includes:
    1. adherence to correct radio procedures;
    2. use of correct frequency; and
    3. constant radio watch by all stations on the net.

To prevent confusion on a radio net the following rules must be obeyed:

  • messages should be written down prior to transmission
  • transmissions should be short and concise consistent with clarity
  • natural emphasis on each word and sensible phrasing
  • operators must ensure the net is clear before starting transmission
  • answer all calls immediately and in correct answering order
  • ensure press to talk switch returns to receive all transmissions
  • profane or obscene language is not to be used.

  1. PROWORD
    1. Prowords are words or words that have been assigned a meaning for the purpose of speeding Radio traffic between users. This enables one word or phrase to be used in place of a complete sentence.
    2. The following PROWORDS are the most common ones, we as 39BN will be using:
      1. ACKNOWLEDGE - Instruction to a callsign on the net to acknowledge that it has heard a message which may not have been specifically addressed to it.
      2. ROGER - I have received your last transmission satisfactorily.
      3. GRID - Used before any GR lets receiver know that numbers are to sent.
      4. I SAY AGAIN - Used by sender when making repetitions for emphasis or in response to request to say again.
      5. OUT - This is the end of my transmission. No reply is required or expected.
      6. OUT TO YOU - This is the end of my transmission to you. No reply is expected and a call to another station follows immediately.
      7. RADIO CHECK - Report signal strength and readability.
      8. FETCH - Used in conjunction with an appointment title to indicate to whom the caller wishes to speak.
      9. SEND - I am ready to receive your message.
      10. THIS IS - Indicates identity of calling station.
      11. WAIT OUT - Your transmission is received; a further transmission on the same subject will follow later. Other stations may continue transmitting as normal.
      12. WILCO - Message received, understood and will be complied with
      13. CONTACT - all callsigns stop taking and wait for the Contact Callsign to give details about the contact
      14. OVER - This is the end of my transmission to you; a reply or acknowledgement is required, go ahead and transmit.
      15. READ BACK - Repeat this entire transmission back to me entirely as received.
      16. SPEAKING - Used in conjunction with an appointment title, to indicate who is speaking.
      17. UNKNOWN STATION - The identity of the station I am calling is unknown to me.
