OVERVIEW: The 100mm HEAT (High-Explosive Anti-Tank) round for the 2A70 gun is designed to defeat armored threats through shaped charge technology. It is commonly employed by Russian and export infantry fighting vehicles equipped with the 2A70 low-pressure rifled gun, such as the BMP-3.

GENERAL DESCRIPTION: The HEAT round for the 2A70 gun is fin-stabilized and features a shaped charge warhead capable of penetrating armor using a focused explosive jet. Unlike kinetic penetrators, HEAT rounds do not rely on velocity, making them effective at all ranges. These munitions are typically loaded as part of a two-part ammunition system (separate projectile and propellant charge). The 2A70 is a low-recoil cannon, enabling firing from lighter platforms such as IFVs.
