A parka and anorak is a type of coat with a hood, often lined with fur or faux fur. These two kinds of garments are staple of Inuit clothing, traditionally made from caribou or seal skin, for hunting and kayaking in the frigid Arctic. Some Inuit anoraks require regular coating with fish oil to retain their water resistance. Parkas are typically longer, often extending to the thighs or knees. Anoraks are usually shorter than parkas, often hip-length, and are traditionally a pull-over jacket.
A balaclava, also known as a monkey cap, balaclava helmet, ski mask or sheisty, is a form of cloth headgear designed to expose only part of the face, usually the eyes and mouth. Depending on style and how it is worn, only the eyes, mouth and nose, or just the front of the face are unprotected. Versions with enough of a full face opening may be rolled into a hat to cover the crown of the head or folded down as a collar around the neck. It is commonly used in alpine skiing and snowboarding.
Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure. Spalling and spallation both describe the process of surface failure in which spall is shed.
Extreme cold weather clothing is clothing for arctic or mountainous areas. Its primary function is to trap air as an insulator to prevent heat loss from the wearer's body. Secondary and necessary is to conduct water vapor away from the body to keep the insulating layers dry. A shell keeps the wind from disturbing the still air in the insulating layers. In warmer conditions, the shell protects from water intrusion.
The Army Combat Uniform (ACU) is the current combat uniform worn by the United States Army, U.S. Air Force, and U.S. Space Force. Within U.S. Air Force and U.S. Space Force, it is referred to as the OCP Uniform, rather than the Army Combat Uniform.
Military vehicles are commonly armoured to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships.
A boilersuit, also known as coveralls, is a loose fitting garment covering the whole body except for the head, hands and feet.
A flight suit is a full-body garment, worn while flying aircraft such as military airplanes, gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical, and durable. Its appearance is usually similar to a jumpsuit. A military flight suit may also show rank insignia. It is sometimes used by Special Forces as a combat uniform in close quarters battle or visit, board, search, and seizure situations, for its practicality.
Armour with two or more plates spaced a distance apart falls under the category of spaced armour. Spaced armour can be sloped or unsloped. When sloped, it reduces the penetrating power of bullets and solid shot, as after penetrating each plate projectiles tend to tumble, deflect, deform, or disintegrate; spaced armour that is not sloped is generally designed to provide protection from explosive projectiles, which detonate before reaching the primary armour. Spaced armour is used on military vehicles such as tanks and combat bulldozers. In a less common application, it is used in some spacecraft that use Whipple shields.
The Jacket, Field, O.D. is a field jacket that was used by US Army soldiers, most famously during the beginning of World War II. In 1941 it started to be phased in as a replacement for the wool four-pocket service coat of World War I, but around 1943 it was replaced in turn by the improved M1943 model. Owing to wide adoption, the M1941 is usually recognized as a symbol of the World War II American G.I. The jacket was made in a light shade of olive drab called O.D. number 2.
Sportswear or activewear is athletic clothing, including footwear, worn for sports activity or physical exercise. Sport-specific clothing is worn for most sports and physical exercise, for practical, comfort or safety reasons.
The Extended Cold Weather Clothing System is a protective clothing system developed in the 1980s by the United States Army Natick Soldier Research, Development and Engineering Center, Natick, Massachusetts. The first generation ECWCS consisted of parka and trousers plus 20 other individual clothing, handwear, headwear and footwear items which are used in various combinations to meet the cold weather environmental requirements of the US military. The Extended Climate Warfighter Clothing System, or Gen III ECWCS, is designed to maintain adequate environmental protection in temperatures ranging between −60 and +40 °F.
Building insulation materials are the building materials that form the thermal envelope of a building or otherwise reduce heat transfer.
The Army Combat Shirt (ACS) is a flame-resistant shirt developed and used by the United States Army as a supplementary addition to the Army Combat Uniform. The ACS is a stand-alone shirt designed specifically for use with Improved Outer Tactical Vest armor in warm and hot weather instead of the blouse. It is intended to greatly increase user comfort through the use of lightweight, moisture-wicking, and breathable fabrics. The ACS was created in conjunction with the USMC's Flame Resistant Organizational Gear (FROG). The ACS, in conjunction with the Fire Resistant ACU (FRACU) trousers, provides head-to-toe protection against burns.
Bunny boots or Mickey Mouse boots are the most common nicknames for the Extreme Cold Vapor Barrier Boots used by the United States Armed Forces. These large, bulbous, waterproof rubber boots can be worn in extremely cold weather, −20 to −60 °F, with the liner-free interior retaining warmth by sandwiching up to one inch of wool and felt insulation between two vacuum-tight layers of rubber; this vacuum layer insulates the wearer's feet similar to a vacuum flask. These boots were originally developed at the Navy Clothing and Textile Research Center in Natick, Massachusetts, for use during the Korean War.
Flame Resistant Organizational Gear (FROG) is clothing used by the United States Marine Corps to reduce the number of injuries resulting from fire and flash, due to the increased use of improvised explosive devices in the wars in Afghanistan and Iraq.
A gable roof is a roof consisting of two sections whose upper horizontal edges meet to form its ridge. The most common roof shape in cold or temperate climates, it is constructed of rafters, roof trusses or purlins. The pitch of a gable roof can vary greatly.
Propper is a manufacturer of clothing and gear for tactical, law enforcement, public safety, and military applications. Since 1967 it has been one of the main uniform suppliers to the United States military.
The Mounted Soldier System (MSS) or Ground Warrior is a combat vehicle crewman ensemble integrating advanced gear as an effective force multiplier in combat theater.
