The M108 Howitzer is an American self-propelled 105 mm howitzer, first introduced in the early 1960s as a replacement for the M52 self-propelled howitzer.[1]

The M108 was powered by a Detroit Diesel turbocharged 8V-71T 8-cylinders 405 hp engine. It used the same hull and turret as the 155 mm M109 self-propelled howitzer, and components of the M113 armored vehicle. The M108 was phased out soon after the American intervention in the Vietnam War, as the M109's 155 mm calibre was considered better fitted for modern war.

The M108 was used by several NATO countries.[2]

Operational history

The M108 in 1961

The M108 howitzer's sole use in combat occurred in the Vietnam War. M108s equipped the first U.S. Army field artillery unit deployed to the conflict, when the 3-6 Field Artillery Battalion was deployed to Pleiku on June 17, 1966. This was soon followed by the 1-40th Field Artillery Battalion to Dong Ha Combat Base in October, 1966. M108s were generally employed from fortified fire bases providing artillery support to units in the field. Because M108 and M109 howitzers could traverse their main gun 360 degrees, unlike towed artillery, they were ideal for holding fire base positions, which might be subject to attack from any direction. Both M108 battalions were withdrawn and phased out of U.S. Army service in 1975.[3]
