M7 Priest

During the early stages of World War II, US Army observers realized that they would need a self-propelled artillery vehicle with sufficient firepower to support armored operations. Lessons learned with half-tracks (such as the T19 howitzer motor carriage (HMC) with a 105 mm howitzer on the M3 half-track chassis) also showed that this vehicle would have to be armored and fully tracked. It was decided to use the M3 Lee chassis as the basis for this new vehicle design, named T32. The pilot vehicles used the M3 chassis with an open-topped superstructure, mounting an M2A1 105 mm howitzer, with a machine-gun added after trials. The T32 was accepted for service as the M7 in February 1942 and production began that April. The British Tank Mission had requested 2,500 to be delivered by the end of 1942 and a further 3,000 by the end of 1943, an order which was never fully completed. ==Operational history==

A total of 3,489 M7s and 826 M7B1s were built. They proved to be reliable weapons, continuing to see front-line service in the US and other armies well past the end of World War II. The British Commonwealth armies had logistical problems in supplying the M7, as it used US ammunition that was not compatible with standard British artillery pieces or tank guns, and had to be supplied separately. as it moves into position to support an attack on Caen, 8 July 1944. During the Battle of the Bulge, each US armored division had three battalions of M7s, giving them unparalleled mobile artillery support. Pacific War The M7 was also used by US and British forces in Pacific and Asian theaters. During the Burma campaign, the Priest played a significant role, in particular, at the Battle of Meiktila and the advance on Rangoon (1945). From early 1944 it was used in the South West Pacific theater, by the US Sixth Army in the later stages of the campaign in New Guinea and surrounding islands. The M7 also saw action in the Philippines campaign, with the US Eighth and Sixth armies. After World War II Korean War M7 Priests remained in use during the Korean War, where their flexibility, compared to towed artillery units, led the US Army on the path to converting fully to self-propelled howitzers. The limited gun elevation of the M7 (35 degrees) hampered its ability to shoot over the tall Korean mountains, so 127 M7B1s were modified to permit the full 65 degrees elevation in a model known as the M7B2. After the Korean War, many of these were exported to NATO countries, notably Italy and Germany. Israel Israel acquired a number of M7 Priests during the 1960s and employed them in the Six-Day War, the War of Attrition and the Yom Kippur War where three M7 units, the 822nd, 827th and 829th Battalions in the IDF Northern Command, supported operations in the Golan Heights. West Germany The new West German received 127 Priests as its first self-propelled artillery vehicle. They entered service in 1956 and were used until the early 1960s. ==Surviving vehicles==

;M7 :The first M7s produced were based on modified M3 Lee medium tank chassis. To maintain a low silhouette, the howitzer elevation had to be restricted to 35°. In May 1942, after only a month of production, the vehicle was altered to increase its ammunition stowage from 57 to 69 rounds. This was achieved by placing seven rounds on the left wall and five on the right. ;M7B1 :Completing the shift, the M7B1 was fully based on the M4A3 Sherman chassis. 826 M7B1 were produced from March 1944 to February 1945. 36 vehicles each were allocated to the 4th Infantry Brigade of the 2nd Canadian Division and the 154th (Highland) Brigade of the 51st (Highland) Division, which led the attack. ;Kangaroo :A Canadian armored personnel carrier conversion of the M7 for use by British and Commonwealth units in northern Europe. The Kangaroo could carry 20 infantry plus a crew of two. A total of 102 were converted between October 1944 and April 1945. The name "Kangaroo" became generic for all conversions of armored fighting vehicles into personnel carriers, including Ram tank conversions. ==British SPG naming scheme==

A British self-propelled gun armed with the Ordnance QF 25-pounder in design from 1941 was nicknamed Bishop as its appearance was said to resemble a bishop's mitre and a replacement, the US 105 mm howitzer motor carriage M7, was called "Priest", as part of its superstructure was said to resemble a pulpit. Following this line of names, a 1942 self-propelled gun armed with the QF 6 pounder was named Deacon and a 1943 weapon carrier with the QF 25-pounder was called Sexton. ==In popular culture==

An altered M37 Priest was used to represent a German Tiger tank in the "Hold That Tiger" episode of the TV series ''Hogan's Heroes'' (season 1, episode 2, first broadcast September 24, 1965). ==See also==
