The M19 multiple gun motor carriage (MGMC) was a World War II United States Army self-propelled anti-aircraft weapon on the M24 light tank chassis.

It was accepted into service in May 1944 as the M19 MGMC, equipping several U.S. Army anti-aircraft units during World War II.

Although all M19s were produced during World War II, they did not reach operational capability until after the cessation of hostilities.

[1][4] The T65E1 was accepted into service as the M19 gun motor carriage in May 1944 with an order for 904 production models,[1][5] which was sent to Cadillac.

[1] The full order was not completed as the requirements for anti-aircraft weapons had changed and chassis were diverted to produce more of the Chaffee light tank.

[8] It was never delivered to other countries for Lend-Lease or through Military Assistance Program (though a few examples were transferred to the Netherlands in 1951 and the newly established JGSDF in 1954).
