Reactive Armor!
Reactive Armor is a type of specialized armor mounted on the surface of modern Earth's advanced tanks.
The reason for its existence is that with the development of modern Earth's technology, the destructive power against tanks has become increasingly strong, with the widespread application of individual anti-tank weapons, continuous upgrades to special ammunition such as armor-piercing bullets and armor-shattering bombs, making tanks extremely vulnerable.
To make tanks less vulnerable, the best method is to crazily increase the thickness of the tank armor. However, when the thickness of the tank armor reaches thousands of millimeters, a problem arises—not a problem of craftsmanship, but one of agility.
