authorized the conversion of two M18 tank destroyers as prime movers for the 3-inch Gun M5 on Carriage M6, a towed antitank gun used by tank destroyer battalions, and armored command and reconnaissance vehicles. The vehicles were respectively designated the T41 and T41E1. Tests were "highly successful," but the Ordnance Department decided that the configuration of the T41E1, which allowed for easy conversion between a prime mover or command vehicle, would suit the needs of the program, so work on the T41 was stopped; when equipped as a prime mover or command vehicle, the vehicles would still respectively be referred to as T41 or T41E1, however. The T41 was equipped with an SCR-610 radio and stowage space for 42 rounds of 3-inch ammunition. It had a crew of two, and could seat up to eight passengers. The T41E1 had an SCR-506 or SCR-608 radio in addition to the SCR-610, with an auxiliary generator. It could carry up to seven passengers. A

and three antitank mines were provided for self-defense in the reconnaissance role. On 26 June 1944, the Ordnance Committee approved the production of 650 T41 prime movers from early M18 Hellcat tank destroyers that had been returned under Ordnance directive to the Buick factory that March to fix problems with their transmission gear ratios, as well as incorporate the latest modifications. In November 1944, the number of T41s to be produced was reduced to 640 and the design was standardized as the Armored Utility Vehicle M39. Ten additional T41s were converted to T41E1 configuration for testing at the request of the European Theater, but the T41E1 was never standardized. Both variants saw limited service beginning in April 1945, immediately before the and of World War II in Europe, in particular because the 3-inch gun had begun to be phased out of service in early 1945 in favor of self-propelled tank destroyers. In March 1945, reports from Europe indicated it would be desirable to develop an armored roof for the open-topped M39.


Korean War

The M39 was more widely used during the Korean War, where they were employed in variety of roles, including as troop transports, armored ambulances, and ammunition carriers for 155mm M41 Gorilla self-propelled howitzers. M39s played a vital role in supplying and ferrying troops to isolated outposts during the later defensive phase of the Korean War, though their thin armor and open tops meant the crews were vulnerable to enemy fire, and the fully enclosed

eventually replaced it in this role.


Ambush in the Battle of Imjin River

M39s were employed as ammunition carriers in the African American 999th Armored Field Artillery Battalion, which fought in the
Battle of the Imjin River The Battle of the Imjin River ( fil, Labanan sa Ilog Imjin), also known as the Battle of Solma-ri ( ko, 설마리 전투) or Battle of Gloster Hill () in South Korea, or as Battle of Xuemali () in China, took place 22–25 April 1951 during t ...
, where it provided artillery support for the 1st Republic of Korea Infantry Division. During the battle, Battery B was forced to evacuate its position after neighboring units withdrew. Because the M39s carriers had .50 caliber machine guns, unlike the unit's M41 self-propelled howitzers, they led the retreating column. During the retreat, it was ambushed by Chinese forces; in the battle, the unit lost seven killed in action, two M39 Armored Utility Vehicles, and had two M41s damaged and 31 wounded. However, the unit broke through the ambush, inflicting an estimated 100 casualties on the ambushing forces, and promptly resumed providing artillery support afterwards. The M39 was declared obsolete in U.S. service in 1957.
