Item Overview
This September 1968 TM 9-2300-216-10 technical manual covers the M107 175mm Self-Propelled Field Artillery Gun and the M110 8-Inch Self-Propelled Howitzer. Written for vehicle crews, this U.S. Army operator's manual brings two major heavy artillery systems together in one reference. It offers a period view of the equipment, controls, and crew tasks that supported these tracked weapons. For collectors, it connects the paperwork of Army service with the machines seen in Cold War and Vietnam War photographs.

Function and Contents
TM 9-2300-216-10 explains the equipment from the operator's point of view. Its illustrated material identifies the driver's controls, gunner's controls, sighting equipment, hydraulic loader and rammer, recoil system, rear stabilizing spade, and travel locks. Vehicle coverage also includes the engine and transmission areas, track-related equipment, and fire extinguishers. These illustrations help readers locate components and understand how the crew's work connected the vehicle with its artillery mount. The manual's focus on crew operation makes it useful for studying the daily handling and care of these systems.
Publication History
The TM 9-2300-216-10 publication series began in June 1962 as the Army introduced this generation of heavy self-propelled artillery. Supporting repair-parts and maintenance publications followed within the same manual family. The September 1968 date places this copy in the Vietnam War period, when both covered systems were in combat service. The publication series remained a working Army reference: the November 1969 issue of Artillery magazine listed TM 9-2300-216-10 among the manuals recommended for battery-level use. Its history reflects the continuing need for clear crew guidance as these vehicles served in the field.
Documented Applications
This publication applies to the full-tracked M107 gun and the original M110 howitzer listed above. It covers a shared vehicle family fitted with two different main weapons. The M107 is identified by its long 175mm gun, while the original M110 carries a shorter 8-inch howitzer. Those differences matter when matching a manual to a museum vehicle, photograph, or model. This dated publication is especially relevant to the original equipment configurations, which preceded the later M110A1 and M110A2 upgrades.
Equipment History
The M107 and M110 belonged to the Army's early 1960s artillery modernization program. The M110 entered service in 1963. Both vehicles used a diesel-powered tracked chassis with an open rear working area and a large stabilizing spade. Their common carrier helped simplify support for two heavy artillery roles. The design gave crews room to work around the weapon, though it left much of the gun crew exposed to weather and enemy fire. Later development produced the M110A1 with a longer howitzer barrel and the M110A2 with a muzzle brake, extending the life of the vehicle family.
Weapon-System Background
The M107 mounted the 175mm M113 gun and could reach targets nearly 33 kilometers, or about 20 miles, away. That range made it valuable for supporting forces across a wide area. The original M110's 8-inch howitzer fired a projectile weighing about 200 pounds to nearly 17 kilometers, or about 10.5 miles. It was known for its accuracy and heavy shell. These weapons gave commanders different strengths: the M107 offered greater reach, while the M110 delivered a larger projectile with strong accuracy. Both supplied heavy fire support beyond the role of lighter field artillery.
History of Use
During the Vietnam War, M107 guns and M110 howitzers supported ground forces from defended artillery positions and fire support bases. Eight-inch howitzers served with division artillery, while both types also served in field force artillery units. Some batteries used a mix of 175mm guns and 8-inch howitzers, with the shared carriage allowing units to adjust their weapon mix as needs changed. Their weight made ground convoys an important means of movement. Service also involved regular crew training and vehicle upkeep. The M110 family continued in Army and Marine Corps service through later models for more than 30 years.
