The Disston had a 37mm gun mounted in the body, and a turret with a .30 caliber (7.62 mm) light machine gun. It weighed about six tons, probably had a speed of 5 to 6.5 miles per hour, and had armor sufficient to stop small arms fire. The crew consisted of three men. At a cost of $21,000 (), the Disston was cheaper than similarly-armed tanks, but – being quite slow, with tracks unsuited for difficult terrain, thin armor, a high boxy superstructure, and the engine exposed in the front – was generally deemed unsatisfactory even so.
