The medium tank M1 never entered service with the US Army. One soft steel pilot was made, since this cost one-tenth as much as constructing a tank out of armor plate. The design was standardized in February 1928, but its standardization was revoked in the spring of that year. The mount for the 6 pdr and coaxial MG permitted some movement of the weapons in addition to the turret rotation.
