Operation 4

Counter-Battery

The first operation where the enemy shoots back — and the largest single drop-off in the campaign. 69.7% of players clear Liberation. Only 50% clear this one.

The IRON NEST instrument wall: rows of gauges, green indicator lamps, valve handles and hanging paper tags across a dimly lit dieselpunk control panel.
Everything on this wall wants attention at once. Counter-Battery is the first operation that does not let you take them one at a time. Screenshot: IRON NEST: Heavy Turret Simulator.

What the mission actually asks

Up to now, targets have waited for you. Here they are guns, they are firing, and they are ranging in on your position while you work. The difficulty is not the arithmetic — it is that the map work now has a clock attached, and the clock is someone else's gunnery.

Two things create every failed run:

  1. You cannot find the enemy guns fast enough.
  2. You find the first wave, kill it, and then a second wave arrives somewhere you have already looked.

Finding guns that are firing at you

A battery that is shooting is telling you where it is. Work the reports rather than sweeping the map:

Your photographs are already out of date

This is the specific thing that ends most runs. Reinforcing artillery arrives as if rolling out of camouflage — and a photograph taken before those guns existed will never show them. A square you photographed, cleared and mentally crossed off can be the battery that is now killing you, and your map will keep insisting it is empty. When a new wave is reported, re-photograph ground you have already covered. Budget requisition for that second flight from the start.

Does moving the NEST help?

Short answer: no, and it is worth knowing before you spend time on it. Players who have tested it report that repositioning does not visibly throw off incoming counter-battery fire, and the developers have said outright that movement was never meant to be a core mechanic. The same goes for the observation and positional units several players have asked about — they do not appear to change the incoming fire.

Treat repositioning as something the mission script asks for, not as a defensive tool. Time spent moving is time not spent finding the guns, and finding the guns is the only thing that stops the shelling.

Working the clock

The time pressure is real, and most of it is self-inflicted. In priority order:

If the timer freezes and nothing spawns

Several players have hit a state where the counter-battery timer sits still, the field report shows nothing new, and the expected second wave never arrives. The pattern points at mission state not fully resetting on a restart, so the game believes a wave has already spawned. The developers have acknowledged and patched timer bugs affecting mission replays.

If you see it: quit to the main menu and start the operation fresh rather than restarting from inside the mission, and make sure you are on the current build.

The Challenge Mode version

Counter-Battery also exists as a scored challenge, and it is a different problem — you are optimising points rather than surviving. What the leaderboard players do:

For calibration: experienced players describe 30–40 points as a solid run. If you are scoring in the twenties, the gap is usually purchasing and sequencing, not gunnery.
