OVERVIEW: 115mm High-Explosive Anti-Tank (HEAT) ammunition is designed primarily for defeating armored targets, including tanks and fortified vehicles. It uses a shaped charge warhead to penetrate armor by focusing explosive energy into a narrow jet capable of breaching thick armor, making it highly effective in anti-armor combat.

DETAILS: These rounds are commonly fired from 115mm tank guns such as the Soviet U-5TS. The HEAT projectile contains a shaped charge with a metal liner that forms a high-velocity jet upon detonation, penetrating armor through the Monroe effect. HEAT rounds are effective regardless of target range or velocity because their penetration does not rely on kinetic energy but on the shaped charge. They are also capable of causing damage to internal components and crew after penetration. Some variants may include tracer elements for aiming assistance.
