A ten-vehicle T-72 column is moving down the valley. Friendly troops are dug in 400 metres from the target - close enough that every round is the observer's personal responsibility. This is what that call actually sounds like, start to finish, from the forward observer's position.
▶ BEGIN FIRE MISSION
Because friendlies are inside the 600 m danger-close ring, the observer cannot bracket the target - walking rounds back and forth across it would eventually put one short, on top of his own people.
Instead he uses the creeping method: place the first round safely beyond the target, then walk it back onto the target from the far side in measured corrections. No round is ever short.
| Round | Correction | Where it lands | From friendlies |
|---|---|---|---|
| RD 1 | - | 250 m beyond the target | 640 m · outside the ring |
| RD 2 | DROP 100 | 150 m beyond | 545 m |
| RD 3 | DROP 150 | on target | 403 m |
| FFE | FIRE FOR EFFECT | 18 rounds on the column | 403 m |
Every station runs its own signal chain - microphone proximity, automatic gain, transmitter clipping, then the narrow band a radio actually passes. The observer on a handmic, the fire direction center flat and procedural on wire, and the pilot clipped and narrow under rotor noise all sound like different equipment in different places.
Audio is positioned from the observer's location. The gun report reaches you about a second after the tubes fire behind you; the impact you see at 1.7 km arrives roughly five seconds later. Distance dulls it, and the Kiowa doppler-shifts as it crosses.
One heightfield drives all four views. The observer sits on the military crest with verified line of sight; the battery is on level ground with no line of sight to the target - indirect fire from defilade; the friendlies are dug into dead ground.
Digits are spoken fife, niner, tree, fower. Grids are read digit by digit. Every transmission closes with OVER or OUT, and every observer transmission gets a verbatim readback. Press E for the annotations that explain each step.
