OVERVIEW: The 100mm High-Explosive (HE) tank ammunition is intended for use against unarmored targets, infantry, field fortifications, and light vehicles. It has been widely deployed on tanks and self-propelled guns from the mid-20th century onward.

GENERAL DESCRIPTION: This type of round contains a high-explosive filler within a steel shell body and is designed to detonate upon impact or via a time-delay fuze. It is fired from 100mm rifled tank or field guns such as the D-10T (used on T-54/55 tanks) and can deliver significant blast and fragmentation effects. Variants may include point-detonating or dual-purpose fuzes for anti-personnel and light materiel targets.
