Radio checks

Before trainings or operations communication channels must be established and confirmed.

Callsign this is Callsign Radio Check, over.

Response –

Callsign this is Callsign reading you Loud and Clear, out.

Example –

Bravo this is Alpha Radio check, over.

Alpha this is Bravo. Reading you loud and clear, out.

The Radio Check will near enough be the only communication where the receiving party may end on out.
In general, the person initiating the contact is the one to call it out.

Different types of support might be available during operations. Here’s how to call in a Fire Mission.

Callsign this is Callsign requesting Fire Mission.

Callsign this is Callsign send it.

Callsign this is Callsign requesting Number of Rounds of Type of Shell, Type of Spread at Grid Ref. Our grid ref is Grid Ref.

Roger Bravo, 4 Rounds of HE at 0000,0000 Fire for Effect.

Sooner or later soldiers run out of ammunition, missiles for their AT or medical supplies. The means of resupplying the troops will be clarified during the briefing before operations.

HQ Callsign this is callsign requesting Supply Drop of Type of supplies needed at Grid Ref

Alpha This is Popeye. Roger that, supplies inbound at 0000,0000. ETA 7 mikes.

During operations HQ might request a sitrep from troops out in the field. Or one platoon might ask for one of the other because of a concerted operation.
SITREPs are not intended to be in-depth but a momentary report of the situation to let SLs keep the big picture.

Example –

Alpha this is Bravo, requesting sitrep, over.

Bravo this is Alpha. Sitrep as follows. We have reached the overview, fortifications going up. Will be set in 2 mikes, over.

ACE reports might be called in after an engagement to assess the unit’s status. It stands for:

A = Ammo

If your team is low on ammo, give details on it. This can be in general (“low on ammo”) or more specific (“AR low on ammo” or “out of AT rounds”)

C = Casualties

Reply with the status of your squad, how many are up, injured, kia or missing.

E = Equipment

If the team has lost important equipment, state it here. E.g., your vehicle has been destroyed; your squad no longer has access to MG etc.

Example –

Bravo this is Alpha, requesting ACE report, over.

Alpha this is Bravo. Wait out, over.

— information being gathered —

Alpha this is Bravo. ACE report as follows. Ammo, still green. Casualties, we have 5 up, 1 wounded, 1 person still missing. Equipment, no AT available as he’s the person missing; we’re orange on medical supplies, over.
