📋 Step-by-Step Instructions

Step 1: Step 1: Measure Target Distance on Map (Caps Lock)

Open the tactical map, check the grid scale (each main grid is 300m, sub-keypad is 100m, or use a Squad Leader move-marker for exact meters).

Step 2: Step 2: Check the GGCodes Elevation Table

Look up your target distance on the in-browser GGCodes Mortar Rangefinder (e.g. 600m = 1461 MIL).

Step 3: Step 3: Adjust Gunner View Using Mouse Scroll

Aim the mortar azimuth compass toward the target, scroll down to lower milliradians to the exact number, and check the tube bubble level.

Step 4: Step 4: Fire 3-Round Walking Spread

Fire one round at target MIL, adjust +/- 5 MIL for a dispersion bracket, and expect shell impact in 18 to 22 seconds.

❓ Frequently Asked Questions

Does terrain elevation difference affect mortar accuracy in Squad?

Yes! If the target is on a mountain 50 meters above your mortar tube, you must subtract approximately 10 MIL from your elevation setting to compensate for the higher ground.
