The American M2 Light Tank was Tiny

However, the lack of a larger caliber anti-tank weapon quickly became apparent as a significant M2 design shortcoming. In order to remedy the tank’s poor firepower, the M2 was equipped with a 37mm anti-tank gun, capable of firing both high-explosive rounds as well as canister shot.
Despite the M2’s relatively small size, the tank had a full, four-member crew size which consisted of a gunner, driver and co-driver, as well as a commander who pulled double duty as a loader.
