The West German Leopard 2 was the first MBT to use Chobham (ceramic composite) armor.

The Merkava is developed and used by Israel. Unusual front end engine placement.

The US M1 Abrams also used Chobham armor. Latest versions added depleted uranium armor.

The British Challenger is comparable to the Leopard 2 and Abrams in armor and gun.

The Russian T80 uses explosive reactive armor bricks, unlike western tanks.
