The 8 in (203 mm) howitzer, which was replaced by the M110 self-propelled howitzer, is a towed weapon developed prior to World War II as a heavy artillery weapon. The weapon uses NATO standard 203mm ammunition, and was used during World War II, in Korea, and in Viet Nam. In NATO service their prime mission was to fire nuclear rounds which have since been phased out of service. Tests of the prototype T3 howitzer began at Aberdeen Proving Ground in 1939 and the howitzer entered service as the 8 in Howitzer M1. After the Second World War the complete weapon was redesignated the Howitzer, Heavy, Towed: 8 in: M115. Variants of the M110 with a longer barrel includethe M110A1 (no muzzle brake) and the M110A2 (fitted with muzzle brake). In most countries the M115 and the M110 have been phased out of service due to short range. The carriage of the 8 in howitzer is also used to mount the 155 mm Gun M1 (Long Tom), which is still in use with some armies. The carriage consists of equilibrator assemblies, elevating and traversing mechanisms, two single-wheel, single-axle heavy limber, two-axle bogie with eight tyres and two trails. Four spades, carried on the trails, are used to emplace the weapon. In recent years some armies have towed the weapon without the limber.

M110 Self-Propelled Howitzer The M110 is a self-propelled heavy artillery cannon with a crew of 12. Designed to be part of a common family of weapons utilising the same chassis components, the M107 and M110 were essentially the same vehicle mounting different barrels. This full-tracked, self-propelled artillery weapon that fires a 200-pound, eight-inch diameter projectile. The shell leaves the muzzle at a velocity of 2,300 feet per second and can travel more than 18 miles. Ammunition includes standard high explosives, bomblets and high explosive rockets. It is found in some corps artillery units. This howitzer system was designed to provide medium-range, general support artillery fire. Powered by a Detroit Diesel, it is not armored and can travel at a top speed of between 30 an 45 miles per hour. The M110 was built by Bowen-McLauchlin-York of York, Pennsylvania. Widely used in Vietnam, the Army received this howitzer in 1963.

The Mack NO was designed as a prime mover for heavy artillery, with a soft top cab for a five man crew. The models NO-1 through NO-7, starting in 1943 with total production about 2000.A Gar Wood 5MB 40,000 lb. winch was mounted in front and a hoist was mounted at the rear of the bed as a power assist for joining the gun trails of the towed artillery. The huge Mack NO 7 1/2 Ton 6x6 Truck (G532) weighed almost 30,000 lbs empty, could load another 10 tons and pull 25 tons. It was powered by the Mack EY 6 cyl. 707 cid engine with 159hp@2100rpm and 534ft-lb of torque at 800rpm. It had a 5 speed transmission mated to a two speed transfer case.argo body was made of wood.
