Heavy tank
The Char 2C was one of the largest tanks ever produced. At the start of World War II, France and the Soviet Union were the only countries to have inventories of heavy tanks, such as the Char B1, T-35, and KV-1. The Matilda II was designed under the British infantry tank concept which is similar to the heavy tank having thick armor and weighing more than their other tanks. It’s usually separate because they have less firepower with their cruiser tanks (comparable to mediums) at the time having the same main armament but more machine guns. Later war examples were the German Tiger I and II, as well as the Soviet IS series. Note that "heavy" versus "medium" is more a question of tactical roles than weight; the Panther, for example, was a "medium" tank that outweighed most Allied "heavy" tanks.
List of United States Marine Corps battalions
The mission of a tank battalion is to conduct operations ashore utilizing maneuver, armor protected firepower and shock action in order to close with and destroy the enemy, as well as provide expertise in anti-tank operations. Currently, tank battalions utilize the M1A1 Abrams main battle tank and the M88A2 Recovery Vehicle. Tank battalions consist of a headquarters and service company and four or six (4th Tanks) tank companies. Each tank company is equipped with 14 tanks and the H&S Co. has a section of two tanks in the battalion headquarters for use by the battalion CO and XO.
