Build your own armor and penetration overlay.
Armor Penetration Calculator lets you choose exactly what information appears, how it is arranged and how it is colored — from a single compact armor / penetration line to a detailed readout with penetration chance, damage, distance and individual armor layers.
- Create your own layout: combine placeholders with your own text, separators and line breaks. Show only the information you want.
- Color individual parts: keep labels neutral while penetration or chance changes color with the result, highlight spaced armor separately, or apply your own fixed colors.
- Start with a preset: load an example, then edit it into your own Custom layout. Your Custom layout is kept while you browse the built-in presets.
- Preview as you edit: try different armor scenarios and see your layout, text size and colors update in Aslain’s Mod Menu.
- Make it fit your screen: adjust text size and opacity, move the overlay with Ctrl + Alt + drag, and let it follow the game’s interface scaling.
- Choose when it appears: use sniper-only display or keep shell penetration and damage visible without an enemy target.
The calculations use your loaded shell and current vehicle mode, with impact angle, normalization, ricochet, overmatch, tracks, spaced armor and HEAT gap loss taken into account. Optional damage values include supported distance-dependent shell damage and active vehicle-mechanic effects.
Penetration percentages are estimates for a shot hitting the calculated aim point. Dispersion, movement and other in-game factors can change the actual outcome. Damage values describe penetrating hits, not HE splash damage.
