ITEM ACTION

Observer______ Used to record the call sign of the observer.AF/FFE/IS______ Used to record the mission type. Choices are AF (adjust

fire), FFE (fire for effect), IS (immediate suppression,and S (suppression). The blank line is used for othertypes; for example, immediate smoke.

Fire Order and Initial Fire Commands Block

Fire Order and Initial Fire Commands Block ItemsITEM ACTION

FIRE ORDER Used to record the fire order.

INITIAL FIRE COMMANDS

FM Used to check or circle the warning order FIRE MISSION sentto the howitzer(s).

MF Used to record the pieces to follow, pieces to fire, andmethod of fire.


13/33

Sp Instr Used to record any special instructions sent to the

howitzer(s).Sh Used to record the shell, if other than standard, sent to the

howitzer(s).

Lot Used to record the ammunition lot , if other than standard,sent to the howitzers. There are to lot designators (projectileand proppelant) for separate-loading ammunition and onelot designator for the projectile for semifixed ammunition.


14/33

Chg Used to record the charge fired in a fire mission.

Fz Used to record the fuze, if other than standard, sent to thehowitzer(s)


15/33


16/33

in Eff Used to record the method of fire for effect . This is thenumber and shell-fuze combination in effect.

Ammo Exp Used to record the ammunition expenditure . This is thenumber of rounds fired with initial fire commands. The

number of rounds is recorded when computed and circledwhen fired.


17/33

Message to Observer Block

Message to Observer Block ItemsITEM ACTION

MTO Used to record the message to observer for a fire mission.T Used to record the angle T for a fire mission. Angle T is sent to the

observer if it is greater than or equal to 500 mils. The actual valueis recorded and then expressed to the nearest 100 mils before beingsent.

PE Used to record the probable error in range for a fire mission.Probable error in range is sent to the observer when it is greaterthan or equal to 38 meters for an area fire mission or 25 meters fora registration, destruct mission, or FPF.

TF Used to record the time of flight of the projectile for a fire mission.

Tgt Used to record the targetnumber for fire plantargets.

Location Used to record the gridlocation for a fire plan

target.Priority Used to record a check

mark to indicate apriority target.

Firing

Unit

Used to record the unit to fire

for a fire plan targets.Dir,MF,Sh,Fz

Used to record the direction,method of fire, shell, or fuze for a fire mission.

Dev Used to record the deviation correction sent by theobserver.

Rg Used to record the range correction sent by theobserver.

HOBCorr

Used to record the height ofburst correction sent by theobserver. Other items may berecorded in this block, such asFFE, EOM, and so on.


21/33

Subsequent Fire Commands Block

Subsequent Fire Commands Block ItemsITEM ACTION

MF,Sh,Chg,Fz Used to record the method of fire, shell, charge, or fuze if changed from the initial fire commands.

FS Corr Used to record the fuze setting correction formechanical time or VT fuzes.


22/33

Ti Used to record the fuze setting for mechanical or VTfuzes.

Chart Df Used to record the subsequent chart deflection asannounced by the HCO once the observers correctionshave been applied.


23/33

Df Corr Used to record the deflection correction for a mission. Inlow-angle fire, this will be the same as the initial

deflection correction. In high-angle fire, drift isdetermined for each round and recorded here.

Df Fired Used to record the deflection to fire sent to thehowiter(s) for subsequent rounds.


24/33

Chart Rg Used to record the subsequent chart range asannounced by the HCO once the observers correctionhave been applied.

HOB Corr Used to record the height of burst correctiondetermined for a fire mission.

SI ( ) Used to record the site for a fire mission. This willnormally be the same as the initial site unless it isrecomputed.

El Used to record the elevation determined by the

computer for subsequent rounds.


25/33

QE Used to record the quadrant elevation sent to thehowitzer(s) for subseuent rounds.


26/33

Exp and Type Used to record the ammunition expenditure and shell-fuze type . This portion of the record of fire is used toindicate a total number of rounds fired of a particularshell and fuze up to that point in the mission. When theshell and/or fuze changes, the count is restarted and theprevious shell or fuze is recorded. Upon completion ofthe mission, the computer uses this trotal, by type, tosubtract from the ammo count. Place a check markafter the type when this number is subtracted from theunits ammo count. The number of rounds is recorded

when computed and circled when fired.
