Mission 4 of Iron Nest is titled "Counter-Battery," a timed, multi-stage operation where an enemy artillery battery fires back at you and you must locate and silence it.
The mission teaches the counter-battery loop: spot the enemy muzzle flashes, take two or more bearings, triangulate the enemy gun line, then lay your own shells onto that point.
Completing Mission 4 earns the "First Reply" achievement, and the gold medal for this stage rewards destroying the enemy battery within the tight time pressure.
Because recon is costly, you should confirm the enemy battery with the fewest observations possible, then commit a deliberate correction shot rather than spraying shells blindly.
The time pressure means you should pre-set your charge and elevation while the enemy is still firing, so the moment you have a second bearing you can fire without delay.
Sound ranging and flash spotting are the two in-game methods to fix the enemy battery; a scout plane bearing helps if you have air support watching that arc.
A common failure is answering the very first flash — the safer play is to intersect two bearing lines and only then fire the shot that ends the exchange.
The Ballistic Calculator and Counter-Battery Calculator tools on this site let you rehearse the bearing-and-range math before you sit down at the turret for this mission.
