Mission 01: Calibration Fire Walkthrough & Solutions | Iron Nest
Master the foundational Iron Nest firing loop without combat pressure: line measurement, powder charge selection, gun elevation, and breach loading.
Mission Summary & Rapid Solution TL;DR EXECUTION
Mark the target on the map, draw a line from the bottom spike of Iron Nest to the target (6.40 km, bearing 45.0°), select 2 powder charges, elevate gun to 32.0°, load H shell, and fire.
- ✓ Read teleprinter briefing and note origin coordinates
- ✓ Draw bearing and range line from Iron Nest bottom spike to Target A
- ✓ Load 2 powder charges and 1 High Explosive (H) shell
- ✓ Traverse turret to 45.0° and set elevation to 32.0°
- ✓ Fire calibration shot and confirm target destruction
Mission Briefing
Calibration Fire is the proving ground for every new Iron Nest operator. There are no enemy counter-battery salvos, no moving targets, and no friendly-fire risks. The primary objective is to build muscle memory for the 6-Step Firing Loop:
- Read the teleprinter order completely.
- Locate Target Alpha on the grid.
- Calculate bearing and distance from Iron Nest.
- Prepare powder charges and High Explosive (H) ammunition.
- Traverse & Elevate the gun barrel.
- Fire and confirm detonation.
Step-by-Step Tactical Solution
1. Grid Measurement
- Iron Nest Coords:
H3 5.5 - Target Alpha Coords:
T8 4.1 - Select your map ruler tool. Anchor the start point at the bottom needle of the Iron Nest marker and extend the line to Target Alpha.
- Measured Range:
6.40 km - Measured Bearing:
045.0°
2. Ballistics Calculation
- At
6.40 km, the target falls in Tier 2 (5.0 - 10.0 km). - Load 2 Powder Charge Bags.
- Mental Multiplier for 2 charges:
5.0. - Estimated Elevation:
6.40 × 5.0 = 32.0°.
3. Gun Preparation & Firing
- Walk to the ammunition rack and select a standard H (High Explosive) round.
- Insert the shell into the open breech, followed by 2 charge bags.
- Close and lock the breech lever.
- Rotate the traverse wheel until the heading indicator displays
045.0°. - Crank the elevation wheel until the inclinometer reaches
32.0°. - Pull the firing lanyard. Confirm direct impact on Target Alpha.
>Frequently Encountered Tactical Problems
Q1Where should I start drawing lines from the Iron Nest icon?
Always draw lines starting from the sharp spike at the bottom of the Iron Nest map icon. Drawing from the center or top of the icon introduces parallax error and causes shots to fall short or wide.
Q2Does bearing affect elevation calculation?
No. Gun elevation is determined strictly by target range (distance) and the selected powder charge count. Turret bearing only controls horizontal rotation.
