Description:
CoB Ballistics – Realistic Terminal Ballistics

Cover is no longer binary. Choose your walls wisely.

Physics-based bullet penetration, ricochets, spalling, fragmentation, grenade interactions, and artillery overpressure for Arma 3. Based on Farrar & Leeming, "Military Ballistics." No dependencies — optional CBA for in-game settings.

Features

Wall Penetration — Bullets punch through walls with reduced velocity. 7.62mm tears through wood, .50 cal gets through brick, 5.56mm stops at concrete.

Spalling — Heavy rounds on brick/concrete send wall fragments off the back side. Lethal even when the bullet doesn’t make it through.

Ricochets & Sparks — Grazing hits on hard surfaces skip off with visible sparks. Metal impacts (vehicles, containers, tin roofs) produce spark bursts.

Fragmentation — Grenades spray fragment projectiles in all directions on detonation. HEAT rockets produce a forward-biased fragment cone on impact.

Grenade Penetration — Grenades fly through glass windows and thin wooden doors. Bounce off concrete. Blast wave passes through walls with material-dependent attenuation.

Artillery — Craters, structural damage, and overpressure. Blast travels through walls — get behind thick concrete.

12 Materials — Glass, thin/thick wood, brick, thin/thick concrete, thin/thick metal, sandbags, earth, light armor (APCs/MRAPs), heavy armor (tanks).

Armored Vehicles — The mod steps aside for tanks, APCs, and MRAPs. Engine/ACE handles armor damage natively.

What Stops What

5.56mm: Glass, thin wood, thin metal. Stopped by brick+.
7.62mm: Also thick wood. Stopped by brick+.
12.7mm: Brick, thin concrete, thick metal. Stopped by thick concrete+.
RPG/HEAT: Warhead diameter-based. Gets through almost everything.
APFSDS: Only heavy tank armor has a chance.
