Main battle tankA main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armor allowed for the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank.
AR-15–style rifleAn AR-15–style rifle is any lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, itself a scaled-down derivative of the AR-10 design by Eugene Stoner. ArmaLite sold the patent and trademarks for both to Colt's Manufacturing Company in 1959 after the military rejected the design in favor of the M14. After most of the patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the rifle under various names.
Rate of fireRate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid.
ArquebusAn arquebus (ˈɑːrk(w)ɪbəs ) is a form of long gun that appeared in Europe and the Ottoman Empire during the 15th century. An infantryman armed with an arquebus is called an arquebusier. The term arquebus is derived from the Dutch word Haakbus ("hook gun"). The term arquebus was applied to many different forms of firearms from the 15th to 17th centuries, but it originally referred to "a hand-gun with a hook-like projection or lug on its under surface, useful for steadying it against battlements or other objects when firing".
Booby trapA booby trap is a device or setup that is intended to kill, harm or surprise a human or another animal. It is triggered by the presence or actions of the victim and sometimes has some form of bait designed to lure the victim towards it. The trap may be set to act upon trespassers that enter restricted areas, and it can be triggered when the victim performs an action (e.g., opening a door, picking something up, or switching something on). It can also be triggered by vehicles driving along a road, as in the case of improvised explosive devices (IEDs).
Bomb disposalBomb disposal is an explosives engineering profession using the process by which hazardous explosive devices are disabled or otherwise rendered safe. Bomb disposal is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the public safety roles of public safety bomb disposal (PSBD) and the bomb squad. The first professional civilian bomb squad was established by Sir Vivian Dering Majendie.
Chobham armourChobham armour is the informal name of a composite armour developed in the 1960s at the British tank research centre on Chobham Common, Surrey. The name has since become the common generic term for composite ceramic vehicle armour. Other names informally given to Chobham armour include Burlington and Dorchester. Special armour is a broader informal term referring to any armour arrangement comprising sandwich reactive plates, including Chobham armour.
BayonetA bayonet (from French baïonnette) is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, carbine, musket or similar firearm, allowing it to be used as a spear-like weapon. From the early 17th to the early 20th century, it was a melee weapon used by infantry for offensive and/or defensive tactics. Today, it is considered an ancillary weapon or a weapon of last resort, although it is still used for ceremonial purposes.
