IRON NESTUnofficial Field Manual

Operator workflow terms

Teleprinter — The station that delivers an assignment at the start of the operating sequence. Its message supplies the context the player carries into notes, map work, and the later stages of the mission.

Requisition console — A console connected with obtaining resources between assignments. It belongs to the wider operation and progression of the machine rather than the immediate act of measuring a target or setting the turret.

Operator — The developers' name for the player's role inside the heavy war machine. The Operator receives assignments and works the connected stations by hand. It is a broad role in the game's fiction and workflow, not the name of a multiplayer class.

Mission loop — The full passage of information and action through an assignment. An order is interpreted and noted, the tactical map supplies measurements, fire control turns those measurements into a setup requirement, the gun is prepared and fired, and the result is reviewed before the next assignment. The term describes the sequence, not a solution to a particular mission.

Map, gunnery, and fire-control terms

Bearing — Horizontal direction written as an angle. On the tactical map, a bearing only makes sense with the points or marker context that establish where the direction begins and what it refers to.

Grid coordinate — A location reference written in the tactical map's grid notation. A coordinate identifies a place through that grid system; it answers a different question from a bearing, which gives direction, or a distance, which gives separation.

Recon marker — A map marker tied to reconnaissance information. It helps show what the current intelligence has revealed and should be read as part of the map state visible at that moment.

Impact point — The mapped location of a shell impact. It records where the event is represented on the tactical map, giving the Operator result information to compare with the other markers and readings already present.

Elevation — The gun's vertical angle. In the described workflow, required elevation comes from the ballistic-calculation stage and is then applied during turret setup. Elevation may share a degree symbol with bearing, but the two angles describe different directions.

Powder charge — A loading and preparation element used alongside the chosen ammunition. Its role belongs between calculation and firing. The available source material names that relationship without providing a universal charge table.

Ballistic calculator — The in-game system that receives measurements from the map stage and returns the required elevation in the developer-described sequence. It is part of game fire control and is separate from the general angle converter hosted on this site.

Rotation — The horizontal positioning of the turret. Rotation and elevation are paired during setup because one turns the gun around the horizontal plane while the other changes its vertical angle.

Mode and progression terms

Campaign — The story mode, built around a narrative sequence of assignments. Choose this term when discussing the main story route rather than the repeatable structure and ranking attached to Challenge play.

Challenge Mode — The replay-focused mode with varied targets, unlockable ammunition, reconnaissance abilities, progression, and Steam leaderboards. Its repeated runs make it distinct from the story-led Campaign even though both draw on the same operating language.

Chill Mode — A named scoring variation in which cumulative confirmed kills are tracked. That differs from the referenced Challenge rule based on the highest score achieved in one correctly completed run.

Steam leaderboard — Steam ranking functionality associated with Challenge play. The described rules cover when a qualifying score is saved and how equal scores are ordered, so the leaderboard is more specific than a general record of everything completed in the game.

General converter terminology

NATO mil — An angular convention that divides a full circle into 6,400 equal parts. A quarter circle is therefore 1,600 NATO mils. Keep the NATO label attached because other conventions divide the circle differently.

6000-circle artillery mil — An angular convention with exactly 6,000 parts in a complete circle. The same numerical mil value produces a different angle under this convention than it does under the 6,400-part NATO convention.

Milliradian (mrad) — One thousandth of a radian. A complete circle contains 2π × 1,000 milliradians, approximately 6,283.185307. It is mathematically defined and is not identical to either rounded artillery convention.

Degrees — An angle convention that divides a complete circle into 360 parts. The reviewed game material expresses angles in degrees. The site's converter can translate between degree and mil conventions, but conversion alone does not supply the other information needed for a game firing solution.

Frequently Asked Questions

The Operator, workflow, map, fire-control, mode, and progression sections define terms used in developer or Steam material. The converter section is explicitly general mathematics for a separate site tool.

Reviewed game material uses degrees and does not document mil input. The mil entries explain the separate converter.

No. The ballistic calculator belongs to the game's fire-control sequence. The site converter only changes how an angle is represented under a selected mathematical convention.
