ELI5: Explain Like I'm 5

High-explosive anti-tank

Okay, let's imagine you're playing with your toy cars and one of them is a really tough one that no other car can smash. That car has a super strong armor that makes it almost impossible to destroy. But what if you had a toy that was so tough and powerful that it could break through that armor? That's kind of like what a high-explosive anti-tank (HEAT) weapon does.

HEAT weapons are made to destroy tanks, which are very tough vehicles that can withstand a lot of damage. But an HEAT weapon is so strong that it can break through a tank's armor and explode inside, causing a lot of damage and maybe even destroying the whole tank.

The way it works is pretty cool. The weapon has a special pointy part at the front called a shaped charge. When the weapon is fired, the shaped charge hits the tank's armor and creates a really hot jet of metal that shoots through the armor like a hot knife through butter. That jet of metal then explodes inside the tank, causing a lot of damage.

So basically, an HEAT weapon is like a super strong toy that can destroy tough toy cars (or real tanks). It uses a special pointy part to break through the toy car's armor and explode inside, causing a lot of damage.
