Which designation refers to High Explosive Incendiary with Tracer?

Explanation:
Understanding how ammunition designations work helps you read these quickly: each part of the acronym signals a feature of the round. The presence of a tracer is shown by the final letter, so a designation that ends with a “T” indicates tracer capability. This is why the designation for High Explosive Incendiary with Tracer is the one that includes the tracer component, i.e., HEIT. Without the tracer, it’s just High Explosive Incendiary (HEI). The other options mix in armor-piercing features (SAPHEI, API) and don’t specify a tracer, so they don’t match the requirement of having a tracer.
