T18 Howitzer Motor Carriage

T18 howitzer motor carriage(T18 HMC) was an American self-propelled gun. Its development started in September 1941 as a close-support vehicle using the M3 Stuart's chassis. A 75mm howitzer was mounted on the right front of the vehicle. Two prototypes were produced and then sent to the Aberdeen Proving Ground. However, they were unsatisfactory because of their high superstructure and nose weight. Because the Army was in favour of M8 HMC, the T18 was abandoned in 1942. Then the prototypes were kept on display in the Aberdeen Proving Ground until they were destroyed in 1947.
