HISTORY
The M7 is a standard towed 105mm M2A1 cannon mounted on an M4 Sherman chassis (earlier version was on the M3 Lee chassis). The need for self-propelled missiles arose already in the first years of the war. The M7 was, among other things, used by the British 8th Army in North Africa, with great success during the Battle of El Alamein. The M7 was included in British and American installations on all front sections in Europe. Was used by the Americans until the end of the 50s.

The M7 was nicknamed Priest because the machine gun mount looked like a pulpit.

Norwegian usage
6 came to Norway with American forces in 1945 and were left behind when the Americans left. The wagons were stored at Ski. A further 3 wagons were received as arms aid after being used during the Korean War. Already in 1951, attempts were made to set up a battery at the AR2, but this was only successful in 1957.

At Haslemoen, the garage doors were too narrow to get the wagons under the roof, nor were the garage doors at the workshop wide enough. There were major challenges in getting the equipment into operation after 12 years of storage. All maintenance had to be done outside under a stretched tarpaulin, and there were almost no spare parts.

In 1960, 22 M7s were received as weapons aid, the carriages had been overhauled in France before delivery. Battery N/Fabatt/Brig N at Setermoen was set up as a self-propelled battery.
The wagons were phased out around 1970, and replaced with the new M109G wagons

Norway also used another, further upgraded wagon, with the changes i have written below

M7B2 Upgrades
During the Korean War, the wagons had a need to be deployed in hilly and uneven terrain. The limited elevation of the gun became a problem, and the M7B2 is a modification that allows elevation of up to 65 degrees. In addition, the machine gun tower was raised to still be able to give the machine gun a 360 degree field of fire.

  • increased elevation of the 105mm cannon from (+35° -30°) to (+65° to -5°)
  • Machinegun tower raised a little to give it the possibility to be turnable 360°

Here is the M7B2 variant at Hjerkinn camp, Norway
