This Technical Manual TM 3-4240-223-15 covers the M14A2 Tank CBR Mask and is dated June 1962. For collectors of U.S. Army technical manuals, Chemical Corps material, Cold War protective equipment, and armored vehicle support literature, this is a strong period reference tied to a specialized and less commonly encountered piece of military protective gear.
Issued in the early Cold War period, this manual belongs to the era when the U.S. military maintained extensive technical literature for chemical, biological, and radiological defense equipment. Manuals like this were working documents, intended to support the identification, use, care, and service understanding of military equipment in actual issue and training environments. That makes this publication especially useful for collectors, researchers, and restorers who want original service-era documentation rather than later summaries or general references.
The M14A2 Tank CBR Mask
The M14A2 Tank CBR Mask belongs to the broader family of U.S. military protective masks and armored-vehicle crew protection equipment. As identified by its nomenclature, it was a tank mask intended for use in a CBR environment, placing it squarely in the support side of Army chemical-defense operations rather than in the category of conventional weapons or vehicle hardware.
A mask of this type was associated with the need to protect armored vehicle personnel operating in enclosed or semi-enclosed fighting compartments where airborne chemical, biological, or radiological hazards were a concern. That makes this manual especially interesting because it documents the technical side of Cold War protective systems tied specifically to tank and armored crew use rather than more general field equipment.
For collectors, the M14A2 is a useful example of how the Army adapted protective equipment to specialized roles. Instead of a standard general-purpose field mask, the tank mask represents a more specific solution tied to the operational needs of armored crews.
What This Manual Covers
As a technical manual, TM 3-4240-223-15 would have supported the Army’s official documentation framework for the M14A2 Tank CBR Mask.
In practical terms, a manual like this is especially relevant for:
That makes it useful not only as a collectible, but also as a practical reference for anyone studying how the Army documented specialized protective equipment during the early 1960s.
Historical Significance
The date June 1962 places this publication squarely in the Cold War period, when the U.S. military maintained extensive technical literature covering chemical defense, protective masks, filtration, decontamination, and protected-environment support systems. Manuals like this reflect a period when Army documentation extended far beyond weapons and vehicles to include the equipment required to help crews remain operational in hazardous conditions.
For collectors and historians, this manual is especially relevant to subjects such as:
Because it covers a specialized tank mask rather than a more common field mask or weapon system, it also adds variety to collections that already include standard ordnance or maintenance manuals.
About This Manual
This listing is for Technical Manual TM 3-4240-223-15 for the M14A2 Tank CBR Mask, dated June 1962.
It is especially well suited for:
Because manuals were working documents, surviving examples are valued not only for their content, but also for their connection to real military training, maintenance, and support practice.
Why This Manual Matters
Many military manuals focus on weapons, vehicles, or combat systems. This one documents the support side of military readiness, specifically protective equipment intended for armored crews operating in hazardous environments. That makes it especially useful for collectors who want to preserve the broader technical and logistical picture of Army Cold War preparedness rather than only front-line hardware.
For collectors, it is a solid stand-alone Cold War technical manual with a specialized subject focus. For researchers, it offers a useful reference point for Army protective-mask documentation and armored crew CBR equipment. For museums, it helps explain the behind-the-scenes systems that supported vehicle crews in contaminated or hazardous conditions.
