Introduction

The tactical map is your primary intelligence tool and the first step in every fire mission. The 20x10 grid with subcells allows precise coordinate plotting for target acquisition and range measurement. Red, yellow, and white pencils mark different information types — active targets, planned fire missions, and completed engagements. Spotter triangulation from two observation points locates targets with bearing line intersection, and the Iris tool previews blast radius before you fire, preventing wasted shells on targets outside effective range. Mastering map operations directly translates to firing accuracy, and every mistake in coordinate plotting compounds through the ballistic calculator into missed shots downrange.

Coordinate System

20x15 grid with alphanumeric references for precise target location

Grid Size20 columns × 15 rows Proficiency with this map tool directly improves fire mission accuracy and reduces the time between target acquisition and successful shell delivery on target.
PrecisionThe 20x10 grid with subcells provides precision down to 10m resolution for coordinate plotting. Each cell is identified by a letter-number code that maps directly to the spotter reporting system.
NotationAlways mark your battery position on the map before plotting any targets. All range and bearing measurements are relative to your known position — without a self-marker, every subsequent plot accumulates positional error.

Spotter Triangulation

Use multiple observer positions to pinpoint exact target coordinates

ObserversMinimum 2 spotters needed for triangulation Proficiency with this map tool directly improves fire mission accuracy and reduces the time between target acquisition and successful shell delivery on target.
AccuracyRed pencil marks active targets currently requiring fire missions. This color convention prevents confusion during batch targeting when multiple fire missions are in progress simultaneously on the same map.
MethodUse distinct pencil colors for each mission phase: red for active targets, blue for planned targets, green for completed engagements, and yellow for spotted but unconfirmed contacts.

Pencil & Iris Tool

Drawing and measurement tools for tactical map annotations

PencilThe Iris tool previews blast radius coverage for a given target coordinate before you fire. This prevents wasting shells on targets outside effective range and helps you select the shell with the smallest adequate blast radius for efficiency scoring.
Iris ToolSpotter triangulation from two observation points uses bearing line intersection to pinpoint target positions. The accuracy of the fix depends on the angle between the two bearing lines — closer to 90 degrees yields the most precise location.
ManagementCalibrate the Iris tool at the start of every session by measuring a known-distance landmark. If the reading deviates from actual distance, note the offset and apply it as a correction factor for all subsequent measurements.

Range Estimation

Visual and mathematical methods for determining target distance

MethodsMap scale, known landmarks, and reticle comparison Proficiency with this map tool directly improves fire mission accuracy and reduces the time between target acquisition and successful shell delivery
AccuracyBearings measured from the compass rose on the map table translate directly to traverse handwheel settings. Always double-check bearing conversions against the compass rose to prevent left-right confusion.
PracticeRange estimation from the map scale is the most error-prone step in the firing loop. Use the Iris tool to verify distances rather than relying on visual estimation, especially at ranges beyond 2000m.

Core Mechanics

The tactical map is the operator's primary tool for target acquisition and fire mission planning. It uses a military grid reference system where the 20×10 operational area is divided into numbered sectors and lettered sub-sectors, allowing precise coordinate notation like "7B-3". Four key tools work together on the map: the coordinate grid for precise position plotting, spotter triangulation (intersecting two or more bearing lines from different observation posts to pinpoint a target), the Iris range-finding tool for measuring distance to visible landmarks, and pencil management for drawing bearing lines, danger zones, and firing corridors. Spotter reports arrive as encrypted messages with bearing and estimated range — operators must decode these, plot the lines on the map, and calculate the intersection point. The pencil system allows multiple concurrent fire missions to be tracked with different colored markers. Map accuracy directly impacts every downstream calculation: a 100m error in target plotting becomes a 100m error at impact. The tactical map section also covers coordinate conversion, dealing with incomplete spotter data, and map tool maintenance.

Advantages

The tactical map provides a comprehensive command-and-control interface that centralizes all target intelligence into a single visual workspace. The military grid system ensures precision — operators can specify target locations to within a few meters using standard coordinate notation. Spotter triangulation converts multiple bearing reports into exact positions, while the Iris tool provides independent range verification. Pencil management allows simultaneous tracking of multiple fire missions with color-coded markers, enabling batch targeting and sequential fire planning. The map directly feeds data into the ballistic calculator, creating a seamless workflow from target acquisition to fire solution. Operators who master all four map tools gain a significant advantage in challenge modes, where rapid plotting and efficient mission sequencing directly improve leaderboard scores.

Challenges

The tactical map's primary weakness is its dependency on spotter reports, which arrive as encrypted messages that must be decoded before use. Incomplete or delayed spotter data leaves operators plotting targets with insufficient information, reducing accuracy. The coordinate grid system, while precise, requires training to read correctly — misreading a sector designation by one letter or number causes a 500m+ plotting error. Pencil management becomes unwieldy during high-tempo missions with multiple concurrent targets; colored pencils break, lines overlap, and erasing is difficult on the vellum surface. The Iris tool requires clear visibility and known reference points, both of which can be unavailable during weather effects or in unfamiliar terrain sectors. Triangulation accuracy degrades with distance — two bearing lines from nearby positions produce a wider error margin than lines from distant observation posts, forcing operators to balance speed (close spotters) against precision (distant spotters).

Frequently Asked Questions

What is the largest map mistake beginners make?+
To triangulate a target, you need bearing reports from at least two different observation positions. Plot each bearing as a line on the map from the spotter's position — where the lines intersect is the target location. Three bearings provide even greater accuracy as the intersection zone narrows. Always verify the intersection point against any known landmarks before calculating your fire solution.
How do I use the Iris tool effectively?+
The Iris tool measures distance by comparing the apparent size of a known reference object against its actual size, using an internal optical scale. Point the Iris at a structure or terrain feature with known dimensions, read the distance from the graduated ring, and note it on your map. Calibrate the Iris before each session by measuring a known distance and adjusting if the reading is off.
Should I clear old pencil marks between missions?+
The pencil system uses different colored markers to track multiple concurrent fire missions. Assign one color per mission phase: red for active targets, blue for planned targets, green for completed missions, and yellow for spotted but unconfirmed targets. This system prevents confusion during high-tempo batch targeting where 3-5 missions may be in progress simultaneously.

Quick Tips

💡

Always mark your battery position first on the map before plotting any targets. All bearing lines and range measurements are relative to your known position — if you do not know where you are, you cannot accurately plot where targets are relative to your guns. This practice becomes increasingly important during extended sessions where fatigue and repetition can lead to complacency and costly mistakes.

💡

Use different colored pencils for different mission phases: red for active targets, blue for planned targets, green for completed missions, and yellow for spotted but unconfirmed targets. This color coding prevents confusion during batch targeting when multiple fire missions are in progress simultaneously. This practice becomes increasingly important during extended sessions where fatigue and repetition can lead to complacency and costly mistakes.

💡

Calibrate the Iris tool at the start of every session by measuring a known-distance landmark and comparing the Iris reading against the actual distance. If the reading is off, adjust or note the offset and apply it as a correction factor for all subsequent measurements during that session. This practice becomes increasingly important during extended sessions where fatigue and repetition can lead to complacency and costly mistakes.
