REQUEST FOR FIRE MISSION FORMAT

Standard Format

GRID\POSITION\EXTRA – TYPE – ROUNDS – CONSIDERATIONS – GRID

Hasty Format

GRID – TYPE – ROUNDS – GRID

GRID\POSITION\EXTRA – Always include a physical grid even when calling on marked locations so no confusion occurs on the fire zone. Grids can be 8 figure if needed, ensure you say 8 figure GRID before you call it. A position can use any map reference to help narrow the position or a division of a grid through bearings like NorthWest quadrant. Any other information can be included on the end to help identify the fire zone, keep it short though.

TYPE – The type of round to use, AP, HE, SMOKE. Combinations can also be used.

ROUNDS – The amount of rounds to fire, generally an indication of the spread you want or if a hard target the penetration you need to achieve. Calls for ranging rounds can be made here as well for example 6 range 1 which would mean a single shot will be fired for target adjustment which may be followed by more single adjustments but then 6 rounds will be fired when fire for effect is called.

CONSIDERATIONS – Location of friendly forces if close by is the most common consideration. Other things include the target type and any considerations with it, vehicle halted, infantry in open, infantry in cover, infantry moving west to east.

GRID – Repeat the main grid again to confirm.

FIRE MISSION FORMAT EXAMPLES

GRID 012012
HE
4
FRIENDLIES 300m SOUTH
GRID 012012

Example2:
BUILDING GRID 012012 COURTYARD NORTH SIDE
HE
6
ENEMY IN COVER
GRID 012012

Example3:
CLEARING GRID 012012
SMOKE
8
FRIENDLIES CROSSING FROM WEST TO EAST
GRID 012012

Example4 – Hasty:
GRID 012012
HE
4
GRID 012012

 

FIRE ADJUSTMENTS

Commonly a single round can be used to ‘range’ a position and once the round is on target a fire for effect can be called or a final adjustment can be issued with a fire for effect.

Adjustments are made using UP, DOWN, LEFT, RIGHT which is just NORTH, SOUTH, EAST and WEST on your map so either is acceptable. This is not true IRL but is how we will communicate changes in targeting.

If you are looking at a target to your North and the fall of shot lands between you and the target say 100m short but is inline a call for ‘UP 100 REPEAT’ would mean an adjustment of 100m North with the same shot or shots as before. If you are using a ranging shot you could call ‘UP 100 FIRE FOR EFFECT’ which doubles as the adjustment and the call for the original fire mission.

 

COMMUNICATION

Communicating a fire mission can be a long and detail process, hopefully this breaks it down enough to key info and keep things flowing. Because it can be a long process keep things brief and abbreviated at all times.
THUMPER runs on long range channel 3 as dedicated fire mission channel, the comms required for fire missions takes up to much air time to put on the cmd net or jtac net. THUMPER still listens to CMD net to know whats happening but fire missions go through CH3.

Standard Format

Used for most fire missions.
FO – Request Fire Mission Over
IDFC – Send Fire Mission Over
FO – FIRE MISSION DETAILS
IDFC – CONFIRMATION GRID READ BACK
FO – ACK OR CORRECTION
ISFC – TIME ROUND OUT (time is given in seconds and as individual number ie TWO-ZERO for 20secs)
FO – Splash Over (Radioed on first impact of first round confirms rounds are at least in vicinity)
IDFC – Splash Out (acknowledge team has rounds striking, wait for BDA)
FO – BDA or Adjustment (if BDA finish with fire mission complete – out)

Immediate Fire Format

Used in emergency situations, less accurate and less feedback to firers.
FO – Request Immediate Fire Over
IDFC – Send Fire Mission Over
FO – HASTY FIRE MISSION DETAILS
IDFC – TIME ROUND OUT
FO – BDA or Adjustment (may not be a BDA in immediate but a fire mission complete – out should still occur to release THUMPER for further tasking)
