The M8 is a full-track tractor based on the chassis of the M41 Walker Bulldog light tank.

It was used to tow cargo trailers and artillery such as the Skysweeper 75 mm anti-aircraft gun and the M59 Long Tom gun.

The basic M8 variant could be quickly adapted for carrying projectiles and charges.

Unusually for a tractor, the M8's engine was located at the front of the cab.

The M8 was developed following the failure of the T33 cargo-carrier, which was based on the M24 Chaffee light tank chassis.
