The Christie M1931, known as the Combat Car, T1 in US Cavalry use and Medium Tank, Convertible, T3 in Infantry branch, was a wheel-to-track tank designed by J. Walter Christie for the United States Army using Christie's ideas of an aero-engine and the novel Christie suspension to give high mobility.
The Army drew up a specification for an improved T3 but following disputes with Christie the order - for 5 of the "Convertible Medium Tank T3E2" was given to the American-La France company.

John Walter Christie (May 6, 1865 – January 11, 1944) was an American engineer and inventor. [1] He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 [3] tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
Christie used the experience gained before and during World War I to develop his "Convertible Suspension", which allowed a vehicle to run on either tracks or wheels. Most tanks of the time period weren't durable enough to be drive to the front on their own, so instead were delivered by trucks and then driven to where they were needed.
Patton later worked closely with Christie to improve the silhouette, suspension, power, and armament of the tanks. Christie's ideas had a great impact upon tank tactics and unit organization in many countries and, finally, upon the U.S. Army as well. On 21 November 1930, Douglas MacArthur had been made chief of staff, with the rank of general. [7]
