It is the movement of the steel plates that disrupts the jet, both by feeding more material into the jet's path, and introducing lateral forces to break the jet apart. The effectiveness of the system was amply demonstrated in

It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat

On a weight basis, lighter targets are more advantageous than heavier targets, but using large quantities of lightweight materials has obvious disadvantages in terms of mechanical layout. Certain materials have an optimal compromise in terms of density that makes them particularly useful in this role.

The
Soviets/Russians had a similar composite armour to the West's own "NERA", with rubber sandwiches between plates of steel. This armour was confirmed to be inside the T-72B's "Super Dolly Parton" armour, but is suspected to be inside the T-80A as well, since it is unlikely the Soviets would put

Chobham armour defeats HEAT warheads by disrupting the high speed jet generated by the warhead. The outer steel "burster" plate detonates the shell and protects the composite array from the blast, increasing the armour's multi hit abilities. After making it through the burster plate, the jet
