Function and Contents
This manual supports the identification of repair parts and special tools for organizational maintenance, meaning work assigned to maintenance personnel within the using unit. Parts names and identifying numbers help connect a replacement item with the Army supply system. That information supports parts requests and helps maintenance staff identify what they need for assigned work. The “20P” designation identifies a parts and tools list, while repair procedures were covered in a separate maintenance manual. For researchers, the publication helps explain the connection between vehicle maintenance, parts records, and military supply practices.
Publication History
Dated December 1973, this edition belongs to a period when the M107 and M110 had already seen extensive wartime service. Army units still needed parts references to support the upkeep of their heavy artillery equipment. The technical manual system divided crew instructions, maintenance procedures, and repair parts information among publications with different purposes. TM 9-2300-216-20P served the parts and special tools role at the unit maintenance level. Its date gives collectors a clear reference point when studying Army technical publications and supply records from the early 1970s.
Documented Applications
The documented applications are the original M107 gun and M110 howitzer listed above. Their common tracked carriage allowed related vehicle equipment to be covered in one publication, while their different cannon installations required attention to the correct model. This makes the manual relevant to research on both shared vehicle components and equipment tied to each artillery system. The vehicle FSNs define its end-item coverage; individual repair parts have their own identifying numbers.
Equipment History
The M107 and M110 formed a family of mobile heavy artillery vehicles introduced in the early 1960s. The M110 entered service in 1963. Both carried their cannon on a diesel-powered tracked carriage with an open rear working platform. A large rear spade helped steady the vehicle during firing. This design gave the weapons their own means of movement and left the crew working around an exposed cannon mount. The M110 family later continued in Army and Marine Corps service for more than 30 years, showing the long service life of this heavy artillery design.
Weapon-System Background
The M107's long 175mm gun tube gave it a range of almost 33 kilometers, or about 20 miles. The original M110's 8-inch, or 203mm, howitzer fired a roughly 200-pound projectile to almost 17 kilometers, or about 10.5 miles, and was valued for its accuracy. These different strengths let commanders select long-range coverage or precise heavy fire as needed. Because both weapons used the same carriage, units could change their mix of cannon tubes to suit mission needs. The gun and howitzer were related systems with distinct fire-support roles.
History of Use
Both vehicles saw combat service during the Vietnam War. The M110 supported divisional artillery, while field force artillery used both the M107 and M110 to cover wider areas. Batteries operated from established positions and firebases, supporting friendly forces within range. The wide spread of artillery units increased the demands on supply and maintenance support. Keeping these vehicles ready depended on maintenance personnel and the flow of replacement parts as well as trained gun crews. A parts manual like this helps document the support work behind the better-known history of heavy artillery missions.
