TM 9-3007 Change 1 - 105mm M101 and M101A1 Towed Light Howitzers - January 1967
Item Overview
This January 1967 Change 1 supplement updates TM 9-3007 for the 105mm M101 and M101A1 towed light howitzers. It is intended for use with the original manual issued on October 1, 1953. This dated update adds a Vietnam-era revision to a technical reference first published during the early Cold War.
Identification and Features
Key details identify this change publication and its parent manual:
- Technical manual number: TM 9-3007
- Revision: Change 1
- Change date: January 1967
- Original manual date: October 1, 1953
- Caliber: 105mm
- Covered equipment: M101 and M101A1 towed light howitzers
- Publication type: Technical manual update supplement
Update Function
Change 1 amends material in the existing technical manual and is used alongside the base publication. TM 9-3007 deals with howitzer and component inspection, repair, and rebuilding. Keeping the numbered change with that reference preserves the revision record when comparing maintenance information from different periods.
Documented End-Item Application
The listed end items are the M101 and M101A1 towed light howitzers. Army manuals identify the M101 with an M2A1 carriage and the M101A1 with an M2A2 carriage. This model distinction helps match the publication to the correct equipment record and explains the two howitzer names in the listing.
Publication History
The original 1953 manual described the howitzer under its earlier M2A1 equipment name. Change 1 appeared more than thirteen years later, when the M101 and M101A1 names were in use. The January 1967 issue links the original technical reference with the Army's Vietnam-era maintenance documentation.
Equipment History
The two carriage models differ mainly in their shields. The M2A1 carriage used right and left main shields with a top shield. The M2A2 carriage used a more extensive arrangement of upper and lower sections, flaps, and auxiliary shields. These features give the models visible differences that can be traced in period photographs and preserved equipment.
Parent Weapon-System Background
The M101 family grew from American 105mm howitzer development during the interwar years. Its M2A1 predecessor became a primary U.S. Army field-artillery weapon during World War II. Rock Island Arsenal manufactured key equipment, including recoil mechanisms and carriages. The later M101-series names carried this established towed-howitzer design into Cold War service.
History of Use
The howitzer family served in World War II, the Korean War, and the Vietnam War. In Vietnam, M101A1 batteries remained active as the lighter M102 began reaching artillery units in 1966. These weapons supported ground troops from field-artillery positions and fire support bases. Postwar exports also placed M101-series howitzers with many allied armies, extending the family's service across several decades.
Ideal For
This supplement suits a collection that follows the revision history of Army technical publications. It also adds dated documentation to an M101 or M101A1 restoration archive and supports museum research on Vietnam-era artillery maintenance.
