The Medium A Tank M1921 Pictures

Built by the U.S. Government at the Rock Island Arsenal and similar to current British designs, this unit arrived at Aberdeen Proving Grounds in February 1922. The tank was equipped with the British cable and suspension track design. The track shoes were made of stamped steel with wooden inserts and were free to pivot. The object, besides simplicity and lighter weight was to find a way to keep the tracks from being clogged with mud.

The Christie M1919 Medium Tank Pictures

J. Walter Christie turned his considerable skills in engineering toward military tracked vehicles and came up with the M1919. Both turrets on the M1919 could turn 360 degrees. Tested at Aberdeen Proving Grounds, it turned into a disappointment for Christie and he asked testing to be halted. Christie returned again with the M1921, though rejected, it was a bit of an improvement. Both tanks could run on either track or wheel and was a true engineering marvels for their time.
