The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British for the American Civil War general William Tecumseh Sherman.

In May 1944 the Detroit Tank Arsenal launched production of M4A3s equipped with 105 mm M4 howitzers. The modification happened similarly to the M4 (105) modernization, one of the most serious alterations of the tank's armament to be made. The upgraded turret boasted a 105 mm howitzer in place of the 76 mm cannon, making the tank capable of taking on many German models.

Shermans with the 105 mm cannon did not have wet stowage. Instead, their ammunition was kept in dry stowages, meaning that the storage bins were kept in the center of the battle compartment. The Detroit Tank Arsenal produced 800 M4A3(105)s between February 1943 and September 1943, though the earlier models did not have a cupola.

M4A3(105)s saw combat on the Western Front and in Italy between 1944 and 1945.
