Documented Applications
TM 9-2300-216-20 applies to the M107 gun and M110 howitzer associated with the Federal Stock Numbers listed above. These are full-tracked artillery vehicles built to provide heavy fire support for ground forces. The publication supports the mechanics and maintenance personnel assigned to their units. Its scope includes the carrier equipment needed for movement and the mounted equipment needed for artillery service, making it relevant to both vehicle and weapon-system research.
Publication History
The Army kept technical manuals in use through numbered changes and official reprints. A reprint could bring revised pages together with the existing manual text, giving personnel a working reference with those updates incorporated. The inclusion of Change 1 pages is therefore an important part of this edition's identity. Its November 1973 date places it in the period when these heavy artillery vehicles remained established equipment in the Army's Cold War force.
Equipment History
The M107 and M110 were part of the Army's early 1960s move toward more mobile heavy artillery. The M110 entered service in 1963. Both used a common tracked carriage with diesel power, an open rear working platform, and a large rear spade to steady the vehicle during firing. Their common carrier design gave the two systems many of the same vehicle components. The M110 family continued in Army and Marine Corps service through later models for more than 30 years.
Weapon-System Background
The two weapons filled different heavy artillery roles. The M107's 175mm gun could reach almost 33 kilometers, or about 20 miles, making it valuable for supporting troops over a wide area. The original M110's 8-inch howitzer fired a projectile weighing about 200 pounds to nearly 17 kilometers, or roughly 10.5 miles. It was known for accurate, powerful fire. These differences let commanders choose between longer reach and a heavier projectile according to their support needs.
History of Use
The M107 and M110 served in training and combat during the Cold War, including extensive use in Vietnam. The 8-inch howitzer served with division artillery, while field force artillery used both the 8-inch and 175mm weapons. Their common carriage allowed some units to change their mix of guns and howitzers as needs shifted. Heavy self-propelled artillery moved between positions in ground convoys and fired from established positions, including fire support bases. Widely scattered units depended on regular supply and maintenance support to keep their equipment available.
