A gas mask is an item of personal protective equipment used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respirators, though the word gas mask is often used to refer to military equipment, the scope used in this article. Gas masks only protect the user from ingesting or inhaling chemical agents, as well as preventing contact with the user's eyes. Most combined gas mask filters will last around 8 hours in a biological or chemical situation. Filters against specific chemical agents can last up to 20 hours.
The Patria AMV is an 8×8 multi-role military vehicle produced by the Finnish defence industry company Patria.
Chemical, biological, radiological, and nuclear defense or Nuclear, biological, and chemical protection is a class of protective measures taken in situations where chemical, biological, radiological, or nuclear hazards may be present. CBRN defense consists of CBRN passive protection, contamination avoidance, and weapons of mass destruction mitigation.
HEPA filter, also known as high-efficiency particulate absorbing filter and high-efficiency particulate arrestance filter, is an efficiency standard of air filters.
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres including lead fumes, vapours, gases and particulate matter such as dusts and airborne pathogens such as viruses. There are two main categories of respirators: the air-purifying respirator, in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator, in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants.
The M40 field protective mask was one of various protective masks used by the United States Armed Forces and its allies to protect from field concentrations of chemical and biological agents, along with radiological fallout particles. It is not effective in an oxygen deficient environment or against ammonia.

The S10 CBRN Respirator is a military gas mask that was formerly used within all branches of the British Armed Forces. Following the mask's replacement by the General Service Respirator in 2011, the S10 is now widely available to the public on the army surplus market.
The Service Respirator No. 6 (S6), also known as Respirator NBC S6 No. 1 Mark 1 was a protective gas mask issued to the British Armed Forces. It was developed in the 1950s and issued for general service from 1966 to 1986, when it was replaced by the S10. Currently, the S6 is not used by the British military.
The MCU-2/P is a protective mask used by the United States Air Force and United States Navy, originally designed for the US Army as the XM-30 mask. In December 1982, the U.S. Air Force took over the XM-30 mask development. In 1983, the U.S. Navy requested the first masks off the production lines since the Army mask was no longer in production and the Navy had none. The Air Force agreed, except to get 5,000 masks to support a 1985 Technology Demonstration. Production began in 1985 and some active duty Sailors and Airmen had a new protective mask before Operation Desert Storm in 1991. It replaced the earlier M17 gas mask and is itself scheduled to be replaced by the M50 joint service general purpose mask. The MCU-2/P features a single large lens and a side-mounted filter. A clear or tinted visor and protective hood are used in conjunction with the mask.
The M1117 Guardian, also denoted armored security vehicle (ASV), is an internal security vehicle based on the V-100 and V-150 Commando series of armored cars. It was developed in the late 1990s for service with the United States' Military Police Corps. The first prototypes appeared in February 1997 and serial production of the M1117 commenced between 1999 and early 2000.
The M88 recovery vehicle is one of the largest armored recovery vehicles (ARV) in use by United States Armed Forces. There are three variants, the M88, the M88A1, and the M88A2 HERCULES. The M88 series has seen action in the Vietnam War, the Persian Gulf War, the Iraq War, and the War in Afghanistan, and to a lesser extent during the Kosovo War, where they were deployed to help recover heavy armored vehicles of the Allied ground units. As of 2000, the M88A2 replacement cost was around US$2,050,000.
The Chemical Corps is the branch of the United States Army tasked with defending against and using chemical, biological, radiological, and nuclear (CBRN) weapons. The Chemical Warfare Service was established on 28 June 1918, combining activities that until then had been dispersed among five separate agencies of the United States federal government. It was made a permanent branch of the Regular Army by the National Defense Act of 1920. In 1945, it was redesignated the Chemical Corps.
The M17 Protective Mask is a series of gas masks that were designed and produced in 1959 to provide protection from all types of known chemical and biological agents present. The M-17 was issued to troops in the Vietnam War, and was standard issue for the U.S. Military until it was replaced by the M40 Field Protective Mask for the U.S. Army and USMC in the mid 1990s while the U.S. Air Force and U.S. Navy replaced it for the MCU-2/P Gas Mask in the mid-1980s.
The General Service Respirator (GSR) is a military gas mask designed to replace the previous S10 respirator for the British Armed Forces. It was designed by the Defence Science and Technology Laboratory and Scott Safety in collaboration with the Ministry of Defence, and was manufactured by Scott Safety. Avon Protection now manufactures the GSR from its factory in Melksham after winning the in-service support contract in 2019.
The FM12 CBRN Respirator is a military gas mask produced by Avon Rubber.
Elastomeric respirators, also called reusable air-purifying respirators, seal to the face with elastomeric material, which may be a natural or synthetic rubber. They are generally reusable. Full-face versions of elastomeric respirators seal better and protect the eyes.
The GP-7 gas mask is a civilian gas mask that was produced by the Soviet Union during the Cold War era. The mask was designed to provide protection to civilians against nuclear, biological, and chemical (NBC) agents during the threat of the Cold War. Its military counterpart, the PMK was intended to be used exclusively for military purposes as opposed to the GP-7 which was designed solely for civil defense.
