IRON NEST Beginner's Guide: Your First Firing Solution

The first thing to understand about IRON NEST is that you are not a soldier — you are a machine operator. Your whole job is to turn an order into an accurate shell on target, using the instruments around you. This guide walks you through a single shot so the loop clicks.

Step 1 — Receive the order

Orders come in over the wire. Keep the teleprinter calibrated and watch the radio traffic for incoming coordinates and target priorities. Early on, take your time reading them; later, the clock will not be so forgiving. More on this in the teleprinter and intel guide.

Step 2 — Read the intelligence

An incoming order isn’t just a map pin. Intelligence reports tell you what you’re shooting at — armor, infantry, fortifications — which in turn decides what shell you’ll want. Decide your target before you touch the controls.

Step 3 — Measure on the tactical map

Take the coordinates you’ve been given and measure them on the tactical map. This gives you the raw range and bearing to the target. Accuracy here matters more than anything else — a sloppy measurement means a wasted shell.

Step 4 — Solve the firing problem

Feed your range into the ballistic calculator to find the elevation your gun needs. Heavy shells arc; they don’t fly straight. The calculator turns distance into the angle that drops the round where you want it. Our ballistic calculator guide breaks this down in detail.

Step 5 — Choose your shell

Pick the round that suits the target:

• Armor-piercing for hardened vehicles and emplacements
• High-explosive for soft targets and area effect
• Smoke to screen movement or blind the enemy
• Chemical and incendiary rounds for specialist situations

Step 6 — Set the charge and lay the gun

Set the propellant charge for the range, then traverse (rotate) and elevate the gun to your solution. This is the hands-on heart of the game — you’re physically aiming thousands of tons of steel. See turret traverse & elevation.

Step 7 — Fire and assess

Pull the trigger, then review the aerial reconnaissance photos to see where the round landed. Missed? Adjust your range or elevation and try again. Hit? On to the next order.

Beginner tips

• Trust the procedure, not your gut. Guessing elevation wastes shells. Measure, calculate, then fire.
• Match the shell to the target. The right round makes an easy kill; the wrong one wastes a turn.
• Mind the clock later. Early missions are forgiving; the challenge modes are where speed matters.
• Use the demo to drill. Repeat the loop in the demo until measuring and calculating feel automatic.
