Rolled homogeneous armour

Rolled Homogeneous Armour is like a super tough shield that tanks and other military vehicles use to protect themselves. It's made by stacking layers of metal plates on top of each other and then smashing them together with a big machine called a roller.

The metal plates are made of a really strong kind of steel called armor-grade steel. This steel is very hard to penetrate and can take a lot of hits without breaking.

After the plates are stacked and rolled together, they are heated up to make them even stronger. This heating process is called tempering. It gives the armour even more protection and resistance against things like bullets and explosive blasts.

The thickness of the armour depends on how much protection is needed. Tanks, for example, have very thick armour because they need to be able to withstand attacks from enemy weapons.

In short, Rolled Homogeneous Armour is like a very strong shield made of stacked metal plates that have been rolled together and heated up to make them even stronger.
