A gas mask is a mask 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. The gas mask only protects the user from digesting, inhaling and contact through the eyes. Most combined gas mask filters will last around 8 hours in a nuclear biological chemical (NBC) situation. Chemical specific filters can last up to 20 hours in an NBC situation.
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. "Protective clothing" is applied to traditional categories of clothing, and "protective gear" applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit.
The Merkava is a main battle tank used by the Israel Defense Forces. The tank began development in 1970, and entered official service in 1979. Four main variants of the tank have been deployed. It was first used extensively in the 1982 Lebanon War. The name "Merkava" was derived from the IDF's initial development program name.
The Combat Vehicle 90 is a family of Swedish tracked combat vehicles designed by Sweden's Defense Materiel Administration , Hägglunds and Bofors during the mid-1980s and early 1990s and entered service in Sweden in the mid-90s. The CV90 platform design has continuously evolved in steps from Mk0 to current MkIV with advances in technology and in response to changing battlefield requirements. The Swedish version of the main infantry fighting vehicle is fitted with a turret from Bofors that is equipped with a 40 mm Bofors autocannon. Export versions are fitted with Hägglunds E-series turrets, armed with either a 30 mm or a 35 mm Bushmaster autocannon.
The Monster Manual is the primary bestiary sourcebook for monsters in the Dungeons & Dragons fantasy role-playing game, first published in 1977 by TSR. It includes monsters derived from mythology and folklore, as well as creatures created specifically for D&D. It describes each with game-specific statistics, and a brief description of its habits and habitats. Most of the entries also have an image of the creature. Along with the Player's Handbook and Dungeon Master's Guide, it is one of the three "core rulebooks" in most editions of the D&D game. Several editions of the Monster Manual have been released for each edition of D&D. It was the first hardcover book of the D&D series. Due to the level of detail and illustration included, it was cited as a pivotal example of a new style of wargame books. Future editions would draw on various sources and act as a compendium of published monsters.

The Tank, Infantry, Mk IV (A22) Churchill was a British heavy infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple bogies, its ability to climb steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allied tanks of the war.
The Tank, Infantry, Mk III, Valentine was an infantry tank produced in the United Kingdom during the Second World War. More than 8,000 of the type were produced in eleven marks, plus various specialised variants, accounting for approximately a quarter of wartime British tank production. The many variants included riveted and welded construction, petrol and diesel engines and a progressive increase in armament. It was supplied in large numbers to the USSR and built under licence in Canada. It was used extensively by the British in the North African campaign. Developed by Vickers, it proved to be both strong and reliable, which was unusual for British tanks of the period.

The Ordnance QF 18-pounder, or simply 18-pounder gun, was the standard British Empire field gun of the First World War-era. It formed the backbone of the Royal Field Artillery during the war, and was produced in large numbers. It was used by British Forces in all the main theatres, and by British troops in Russia in 1919. Its calibre (84 mm) and shell weight were greater than those of the equivalent field guns in French (75 mm) and German (77 mm) service. It was generally horse drawn until mechanisation in the 1930s.
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including fumes, vapours, gases and particulate matter such as dusts and airborne microorganisms. There are two main categories: 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 Mk 6 helmet is a type of combat helmet that was the standard of the British Armed Forces as well as another supplied helmet of the UN during peacekeeping operations. The Mk 6 replaced the Mk IV helmet in army service and the RAC helmet in naval service. The jump in MK numbers is thought due to the confusion surrounding the MK IV helmet using the MK V lining, introduced in 1959. The MK 6, introduced into service from the 1980s, is designed to accept modern ear protection, Bowman personal radios, and respirators. The helmet is manufactured by NP Aerospace, and is reported to have an "almost unlimited service life" by the manufacturer.
Osprey body armour is a system of body armour used by the British Armed Forces. The system is in its fourth iteration following extensive development and engagement with front line users.
The Mk III Helmet was a steel military combat helmet first developed for the British Army in 1941 by the Medical Research Council. First worn in combat by British and Canadian troops on D-Day, the Mk III and Mk IV were used alongside the Brodie helmet for the remainder of the Second World War. It is sometimes referred to as the "turtle" helmet by collectors, because of its vague resemblance to a turtle shell, as well as the 1944 pattern helmet.
The BL 9.2-inch Mk I–VII guns were a family of early British heavy breechloading naval and coast defence guns in service from 1881 to the end of World War I. They were originally designed to use the old gunpowder propellants.
