How-to guides
Short, direct answers to the hands-on questions IRON NEST players ask most — the physical tasks the tutorial rushes past. Each one links to the deeper tool or guide when you want the full method.

How do I load and unload a shell?
- Look at the breech and press the interact key to open it.
- Chamber the shell you want. Match the round to the target — the loadout guide covers when to use HE, AP, illumination and the rest of the nine shells.
- To unload, open the breech again and eject the chambered round before loading a different type — you can't change shell with one already seated.
- Close the breech, then set your powder charge and lay the gun.
Tip — Changing shell mid-fire-mission costs you time, so decide your round before you start ranging. Star shells in particular are loaded deliberately, not on reflex.
How do I restart the engine / restore power?
- Find the Master Power Switch in the cab and set it to ON. If the console is dark or the gun won't respond, this is almost always why.
- If the engine has stalled, run the start-up sequence: power on, then engage the generator so the laying motors and lights have power.
- Give it a moment to spin up — the panel lights and dials come alive when the system is live.
Tip — Several missions — the Counter-Battery operation included — won't progress until power is restored, so make it your first action when you spawn in.
How do I use the map measure / blast tool?
- Open Map View with the interact key while looking at the map console.
- Hold the left mouse button and drag across the map. A line measures ground distance; this is also how you eyeball a shell's blast coverage before committing a round.
- Release to clear it. Use it to check the range between your spotters and a target, or to confirm a bracket before you fire.
Tip — For an exact bearing-and-charge answer rather than an eyeball, feed the same observations into the firing planner.
How do I read a forward observer / spotter report?
- A report gives you bearing and/or distance from the spotter, not from your gun. Note which observer each line references.
- Two bearings from two spotters cross at the target. A bearing plus a distance, or two distances, fix it the same way — intersect the lines or range rings.
- Convert that fix into a bearing and range from the Nest, then pick the powder charge for that range.
Tip — This whole conversion is what the planner automates — drop the spotters, enter the report, read your solution. New to it? Start with your first firing solution.
How do I reposition / move the Iron Nest?
- Movement is a requisition card, not a free action. The Move Direction card moves the Nest a set distance in a direction you choose.
- When you're being bracketed, the EMERGENCY MOVE! card relocates you immediately to a new position, pauses the counter-battery timer and adds 120 seconds — a panic button, not a repositioning tool.
- Play the card from your requisition hand, then resume laying the gun from the new position — your firing solutions change once you've moved.
How do I call in and aim the Scout Plane?
- Play the Scout Plane requisition card when you have it in hand.
- You choose the flyover location — pick the grid where you suspect hidden guns or want to confirm a target, not a random patch of map.
- The flyover reveals what's there, so you can range targets your forward observers can't fix.
Tip — This is the key to the second phase of the Counter-Battery mission — players who call it “pure luck” are usually guessing instead of flying the plane over the hidden batteries.
How do I equip the gas mask and read the gauges?
- Press the gas-mask key (G by default) to pull the mask on or off.
- Wear it when the cab fills with smoke or fumes after sustained firing or a near miss; visibility through the lenses is reduced, so take it off once the air clears.
