This Technical Manual TM 9-252 covers the 40mm Automatic Gun M1 (AA) and 40mm Antiaircraft Gun Carriages M2 and M2A1 and is dated January 1944. For collectors of U.S. military technical manuals, World War II antiaircraft artillery references, ordnance publications, and dated government documents, this is a strong period piece tied to one of the most important categories of wartime defensive equipment: mobile antiaircraft gun systems.
Issued during World War II, this manual reflects a time when the U.S. military placed major importance on air defense, vehicle-supported artillery, ordnance maintenance, and standardized field documentation. Manuals like this were official working documents, intended to support the identification, inspection, servicing, maintenance context, and field support of the equipment they covered. That makes this publication especially useful for collectors, historians, researchers, restorers, and museums looking for authentic wartime reference material rather than general background information.
The 40mm Automatic Gun M1 (AA) and Antiaircraft Gun Carriages
The 40mm Automatic Gun M1 (AA) belongs to the broader family of World War II antiaircraft artillery and automatic cannon equipment. As identified by its nomenclature, it was a 40mm automatic antiaircraft gun, placing it within a specialized category of military ordnance associated with air-defense support, field mobility, and wartime artillery systems.
The included Antiaircraft Gun Carriages M2 and M2A1 are an important part of the manual’s subject matter. Gun carriages were essential to the transport, positioning, and support of antiaircraft gun materiel, making this manual relevant not only to the gun itself, but also to the carriage systems that supported its field use.
For collectors, that gives this manual added appeal. It represents the combined technical documentation of both the 40mm automatic gun and its associated antiaircraft gun carriages, making it especially well suited for collections focused on World War II artillery, antiaircraft equipment, U.S. Army Ordnance Department publications, automatic cannon, and wartime technical manuals.
What This Manual Covers
As a technical manual for the 40mm Automatic Gun M1 (AA) and Antiaircraft Gun Carriages M2 and M2A1, TM 9-252 would have served as an official military reference connected to this antiaircraft gun system and its ordnance-support documentation.
In practical terms, a manual like this is especially relevant for:
- nomenclature and identification reference
- World War II antiaircraft artillery documentation
- U.S. Army Ordnance Department reference collections
- automatic cannon and artillery research
- antiaircraft gun carriage reference
- museum and display documentation
- archival and restoration research
That makes it useful not only as a collectible, but also as a practical historical reference for anyone studying how the U.S. military documented antiaircraft gun systems and carriage equipment during World War II.
Historical Significance
The date January 1944 places this publication squarely in the World War II period, when the United States was fully engaged in global wartime operations and maintaining a massive technical documentation system for weapons, vehicles, artillery, aircraft, support equipment, and ordnance materiel.
Antiaircraft systems were an important part of wartime defense, helping protect troops, bases, vehicles, supply areas, and field positions from aerial threats. Manuals like this reflect the technical and logistical structure behind that equipment, preserving the documentation used to support antiaircraft artillery in a standardized military system.
For collectors and historians, this manual is especially relevant to subjects such as:
- World War II U.S. Army technical manuals
- 40mm Automatic Gun M1 documentation
- M2 and M2A1 antiaircraft gun carriage references
- U.S. Army Ordnance Department publications
- World War II antiaircraft artillery manuals
- automatic cannon technical publications
Because it covers both the 40mm Automatic Gun M1 (AA) and the M2 / M2A1 antiaircraft gun carriages, this manual adds strong historical depth to collections centered on World War II artillery, air-defense systems, ordnance equipment, and military technical publications.
About This Manual

Why This Manual Matters
Many military manuals focus on rifles, vehicles, communications gear, or general shop equipment. This one documents a more specialized and historically important subject: the 40mm Automatic Gun M1 (AA) and its related M2 and M2A1 antiaircraft gun carriages. That makes it especially useful for collectors who want to preserve the broader technical and logistical picture of World War II air-defense equipment rather than only the weapons or vehicles themselves.
For collectors, it is a strong stand-alone World War II technical manual with a focused antiaircraft ordnance subject. For researchers, it offers a useful reference point for U.S. Army ordnance documentation during the wartime period. For museums, it helps support displays that explain not only antiaircraft gun systems, but also the technical literature and support structure that kept wartime equipment documented and serviceable.
