High explosive incendiary/armor piercing ammunition is a type of bullet that is used in guns. It is made to be very strong and tough so that it can pierce through things like armor that normal bullets can't.
The bullet has two main parts – the high explosive incendiary part and the armor piercing part.
The high explosive incendiary part is made to explode when it hits something. This explosion can cause a big spark or a fire that can burn whatever it hits.
The armor piercing part is made to be very sharp and strong so that it can cut through tough materials like metal or concrete. This part helps the bullet to pierce through things like body armor that protect people.
When a person shoots this type of bullet at something, like a tank or a fortified building, it can cause a lot of damage. The bullet can pierce through the armor, set things on fire, and cause explosions.
It's important to note that these types of bullets are generally only used in military and combat situations and not for regular civilian use.
