High-explosive incendiary/armor-piercing ammunition (HEIAP) is a form of shell which combines armor-piercing capability and a high-explosive effect. In this respect it is a modern version of an armor-piercing shell. The ammunition may also be called semi-armor-piercing high-explosive incendiary (SAPHEI). [1]

The Improved 25mm x 137 PGU-32/U SAPHEI-T, is designed to provide aerial and surface gun platforms with improved effectiveness against soft and light armored targets. The PGU-32/U incorporates the basic multipurpose technology providing: inherent detonation delay, improved graze sensitivity, and light armor capability.

穿甲弹（英文：armor-piercing munition，简称armor-piercer或AP），是一种用来穿透装甲的弹药，分穿甲子弹和穿甲炮弹两类，前者主要用于击穿单兵护甲和一些具有轻型防护的设备（反器材），后者用来破坏各类重型载具。 “穿甲弹”一词通常指的是穿甲炮弹，从1860年代至1950年代的主要应用是击穿战舰的厚重装甲，从1920年代起也被用于反坦克。 历史. 19世纪下半叶早期开始铁甲舰得以发展，该舰载有相当厚度的锻铁装甲。 这种装甲几乎不受当时使用的圆形铸铁炮弹和 …

SAPHEI是半穿甲高爆燃烧弹 MPAT和HEAT-MP应该是同一个东西，多用途破甲弹 ATGM是反坦克导弹 Tandem ATGM是串联装药反坦克导弹 Thermobaric ATGM是温压战斗部反坦克导弹（实际上是反工事导弹）
