OVERVIEW: 100mm High-Explosive Anti-Tank Fragmentation (HEAT-FRAG) rounds are dual-purpose munitions capable of penetrating armor while delivering fragmentation effects against soft targets and personnel. They are optimized for versatility in both anti-armor and general-purpose support roles.

GENERAL DESCRIPTION: HEAT-FRAG rounds combine a shaped-charge warhead for armor penetration with a fragmentation sleeve or casing that disperses lethal shrapnel upon detonation. This dual-effect makes them suitable for mixed combat environments, where both armored vehicles and infantry or light fortifications may be present. These munitions were commonly used by Soviet and Warsaw Pact tanks and SP guns equipped with 100mm guns.
