Which designation corresponds to High Explosive Incendiary (HEI) ammunition?

• A. Ball
• B. HEI Tracer (HEIT)
• C. API
• D. High Explosive Incendiary (HEI)

Answer: (D)

High Explosive Incendiary rounds are identified by the exact designation High Explosive Incendiary (HEI). This label tells you the payload includes both a high-explosive charge and incendiary material, providing blast and fire effects. A variant with a tracer exists—HEI Tracer—which adds a tracer but is still fundamentally an HEI-type round. Armor-Piercing Incendiary refers to a different category intended for penetrating armor before delivering incendiary effects, and Ball is just a basic round with no special payload. So the designation that corresponds to this ammunition type is the full name High Explosive Incendiary (HEI).
