Description
This Technical Manual Change 1 for TM 9-325 covers updates to the original TM 9-325 manual for the 105mm Howitzer M2A1, 105mm Howitzer Carriages M2A1 and M2A2, and Combat Vehicle Mounts M4 and M4A1. Issued in October 1953, this change notice updates the TM 9-325 manual issued May 7, 1948, making it a strong Korean War / early Cold War-era publication for collectors of U.S. Army technical manuals, artillery references, ordnance publications, and dated government manual updates.
As a Change 1 update, this publication reflects the way U.S. Army technical literature was maintained, revised, and supplemented after initial issue. Manual changes like this were official working documents, intended to keep technical references current for personnel responsible for the identification, care, inspection, and support of the equipment covered. The 1948 TM 9-325 listing identifies the base manual as covering technical information required for the identification, use, and care of the 105mm Howitzer M2A1, carriages, combat vehicle mounts, ammunition, and accessory equipment.
The M2A1 105mm Howitzer, Carriages, and Combat Vehicle Mounts
The 105mm Howitzer M2A1 belongs to one of the most important U.S. artillery families of the mid-20th century. U.S. Army historical material notes that the 105mm howitzer family associated with the M2A1 / M101 line was the standard light howitzer deployed with the U.S. Army during World War II, with production running from 1941 through the end of the Korean War in 1953.
The M2A1 and M2A2 carriages are an important part of this manual’s subject matter. These carriage systems represent the support, transport, positioning, and field-service side of the artillery system, making this manual change relevant not only to the howitzer itself, but also to the carriage equipment that helped define how the system was maintained and supported.
The M4 and M4A1 combat vehicle mounts add additional collector interest because they connect the manual to vehicle-mounted artillery applications. The Army Historical Foundation notes that the 105mm Howitzer Motor Carriage M7 used the 105mm Howitzer M2A1 on the M4 mount, showing the relationship between this howitzer system and self-propelled artillery history.
For collectors, this gives the change notice strong appeal. It represents a specific update to a major artillery manual and fits especially well in collections focused on 105mm howitzer equipment, U.S. Army artillery, Korean War-era technical manuals, early Cold War ordnance documentation, M7 Priest references, and combat vehicle mount history.
What This Manual Change Covers
As Change 1 for TM 9-325, this publication served as an official update to the original manual for the 105mm Howitzer M2A1, Carriages M2A1 and M2A2, and Combat Vehicle Mounts M4 and M4A1.
In practical collecting and historical-reference terms, a manual change like this is especially relevant for:
- technical manual revision history
- 105mm howitzer documentation
- M2A1 and M2A2 carriage reference
- M4 and M4A1 combat vehicle mount research
- Korean War and early Cold War ordnance reference
- U.S. Army artillery support context
- archival and museum documentation
- completing or supplementing a TM 9-325 manual set
That makes it useful not only as a collectible, but also as a supporting reference for anyone studying how the U.S. Army maintained and updated technical documentation for artillery systems after World War II and during the early 1950s.
Historical Significance
The original TM 9-325 issue date of May 7, 1948 places the base manual in the early post-World War II period, while the October 1953 issue date of this Change 1 update places it at the end of the Korean War-era technical publication cycle. Together, these dates show how the Army continued to support, revise, and preserve documentation for artillery systems that remained important after World War II.
For collectors and historians, this manual change is especially relevant to subjects such as:
- TM 9-325 manual revisions
- Korean War U.S. Army technical manuals
- early Cold War artillery documentation
- 105mm Howitzer M2A1 references
- M2A1 and M2A2 carriage documentation
- M4 and M4A1 combat vehicle mount references
- M7 Priest and self-propelled artillery history
Because it is a Change 1 update rather than the base manual, this item has added publication-history value. It helps document the official revision path of TM 9-325 and is especially useful for collectors working to complete a full manual-and-change set.

Why This Manual Change Matters
Many military manuals focus on rifles, pistols, vehicles, communications gear, or general shop equipment. This manual change documents a more specialized and historically important subject: the official update history for the 105mm Howitzer M2A1 and its associated M2A1/M2A2 carriages and M4/M4A1 combat vehicle mounts.
For collectors, it is a strong dated 1953 technical manual change with a focused artillery subject. For researchers, it offers a useful reference point for U.S. Army technical manual revision history during the Korean War / early Cold War period. For museums, it helps support displays that explain not only the howitzer system itself, but also the official publication updates, carriage references, combat vehicle mount documentation, and ordnance support structure behind its service life.
Because manuals and manual changes were working documents, surviving examples are valued not only for their content, but also for their connection to real military documentation, inspection, maintenance support, revision practice, and artillery administration.
