Thompson M1A1

The Thompson was used by American soldiers. Captain Miller, Sergeant Horvath, Captain Hamill and Corporal Henderson used this submachine gun. It uses a .45 caliber bullet and was one of the most reliable machine guns of the war. The large .45 caliber bullet was amazing and more powerful than the German 9 millimeter MP40, thus giving it a deadly and feared reputation, and was made by John T. Thompson. It was later replaced by the M3 grease gun to some extent in 1943, but was still used a lot in Normandy World War 2 in 1944. Since the Grease gun was adopted, more people used M3 Grease Guns, but the Thompson was still the primary Sub Machine Gun.
