  # Voice Procedure

  Voice procedure is a standard way to pass information over a shared radio net.

  Using consistent callsigns and prowords makes transmissions shorter, clearer, and easier to acknowledge.

  ## Basic Rules

  - [bold]Listen before transmitting.[/bold] Do not interrupt traffic already in progress unless the message is urgent.
  - [bold]Plan the message first.[/bold] Know what you need to say before opening the channel.
  - [bold]Use callsigns.[/bold] Do not identify personnel by character name or rank over the radio.
  - [bold]Keep transmissions brief.[/bold] Split long messages into clear sections.
  - [bold]Acknowledge orders and requests.[/bold] Confirm that important traffic was received and understood.
  - [bold]Use plain language.[/bold] Use prowords where they apply, but avoid unnecessary jargon.

  ## Basic Call Format

  Address the receiving station first, then identify the transmitting station.

  [color=#a4885c]HAVOC 6, this is SABRE ROMEO, message, over.[/color]

  A complete call normally contains:

  - The callsign being addressed.
  - [bold]THIS IS[/bold].
  - The transmitting callsign.
  - The message.
  - [bold]OVER[/bold] or [bold]OUT[/bold].

  The receiving station answers using the same order:

  [color=#a4885c]SABRE ROMEO, this is HAVOC 6, send it, over.[/color]

  After both stations have established contact, [bold]THIS IS[/bold] may be omitted:

  [color=#a4885c]SABRE ROMEO, HAVOC 6, send it, over.[/color]

  ## Prowords

  Prowords are standardized words with specific meanings.

  </Table>

  Use [bold]SAY AGAIN[/bold] instead of “repeat” when requesting a repeated radio message. On a fire-support net, [bold]REPEAT[/bold] may be interpreted as an instruction to fire the previous mission again.

  ## Radio Check

  A radio check confirms that two stations can hear each other.

  [color=#a4885c]HAVOC ROMEO, this is SABRE ROMEO, radio check, over.[/color]

  [color=#a4885c]SABRE ROMEO, this is HAVOC ROMEO, Lima Charlie. How me? Over.[/color]

  [color=#a4885c]Lima Charlie, out.[/color]

  When the signal is not clear, describe the problem instead:

  - Weak but readable.
  - Broken.
  - Distorted.
  - Unreadable.

  ## Contact Report

  A contact report should state:

  - What was seen.
  - Where it was seen.
  - Approximate strength.
  - What the reporting element is doing.

  [color=#a4885c]HAVOC 6, this is SABRE ACTUAL, contact. Infantry, squad strength, east treeline near grid two-four-five. Engaging, over.[/color]

  [color=#a4885c]SABRE ACTUAL, HAVOC 6, roger. DAGGER is moving to your flank. Hold your position, over.[/color]

  [color=#a4885c]HAVOC 6, SABRE ACTUAL, wilco, out.[/color]

  ## Fire-Support Request

  Establish contact before sending the full request.

  [color=#a4885c]HAVOC OPS, this is SABRE ROMEO, fire mission, over.[/color]

  [color=#a4885c]SABRE ROMEO, HAVOC OPS, send it, over.[/color]

  The request should identify:

  - The target.
  - The target location.
  - The position of friendly forces.
  - The requested effect.

  [color=#a4885c]Enemy machine-gun position on the north ridge beside the communications tower. Friendlies are two-five-zero meters east, marked by smoke. Request suppression, over.[/color]

  [color=#a4885c]SABRE ROMEO, HAVOC OPS, roger. Rounds out, impact in three-zero seconds, over.[/color]

  [color=#a4885c]HAVOC OPS, SABRE ROMEO, impact observed. Target suppressed. End of mission, out.[/color]

  ## Casualty Evacuation Request

  Establish contact before sending casualty details.

  [color=#a4885c]HAVOC ROMEO, this is DAGGER ROMEO, casualty evacuation request, over.[/color]

  [color=#a4885c]DAGGER ROMEO, HAVOC ROMEO, send it, over.[/color]

  Include:

  - Number of casualties.
  - Medical priority.
  - Pickup location.
  - Condition of the pickup area.
  - Identification or marking.

  [color=#a4885c]Two casualties. One urgent surgical, one walking wounded. Pickup at the landing zone south of the bridge. Area is secure and marked with green smoke, over.[/color]

  [color=#a4885c]DAGGER ROMEO, HAVOC ROMEO, good copy. Evacuation craft inbound in five minutes, out.[/color]

  ## Using ACTUAL

  [bold]ACTUAL[/bold] identifies the person in charge speaking personally rather than an RTO or other person speaking on their behalf.

  Squad leaders carry it as their assigned station: [bold]SABRE ACTUAL[/bold] is the Sabre (Alpha) squad leader. Command stations append it when the officer takes the handset personally.

  [color=#a4885c]SABRE ACTUAL, this is HAVOC 6 ACTUAL. Move past phase line DODGE, over.[/color]

  Without [bold]ACTUAL[/bold], [bold]HAVOC 6[/bold] traffic may be the RTO relaying for the commander. With it, the commander is speaking personally.

  ## Corrections

  Use [bold]CORRECTION[/bold] when an error is noticed during the transmission.

  [color=#a4885c]Enemy infantry west of the bridge, CORRECTION, east of the bridge, squad strength, over.[/color]

  Use [bold]DISREGARD[/bold] when the entire previous message should be ignored.

  [color=#a4885c]DISREGARD my last, out.[/color]

  Brief, structured transmissions leave the net available for acknowledgements and urgent traffic.
