Armour-piercing discarding sabot
Armour-piercing discarding sabot (APDS) is a type of spin-stabilized kinetic energy projectile for anti-armour warfare. Each projectile consists of a sub-calibre round fitted with a sabot. The combination of a lighter sub-calibre projectile with a full-calibre propellant charge allows for an increase in muzzle velocity compared to full-calibre rounds, giving the round increased armour-penetration performance. To further enhance their armour-penetration capabilities, APDS rounds typically feature a hardened core made from tungsten or another hard, dense material.
Artillery observer
An artillery observer, artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see. Historically, the range of artillery steadily increased over the centuries. In the era of bombards or Steinbüchse, the gunner could usually still fire directly on the target by line-of-sight.
Offensive (military)
An offensive is a military operation that seeks through an aggressive projection of armed forces to occupy or recapture territory, gain an objective or achieve some larger strategic, operational, or tactical goal. Another term for an offensive often used by the media is "invasion", or the more general "attack". An offensive is a conduct of combat operations that seek to achieve only some of the objectives of the strategy being pursued in the theatre as a whole.
Elevation (ballistics)
In ballistics, the elevation is the angle between the horizontal plane and the axial direction of the barrel of a gun, mortar or heavy artillery. Originally, elevation was a linear measure of how high the gunners had to physically lift the muzzle of a gun up from the gun carriage to compensate for projectile drop and hit targets at a certain distance. Though early 20th-century firearms were relatively easy to fire, artillery was not. Before and during World War I, the only way to effectively fire artillery was plotting points on a plane.
Weapons platform
A weapons platform is generally any structure, vehicle or mechanism on which a weapon can be installed (via various mounting mechanisms) for optimal stability and performance. The mounted weapons, the platform and all other associated supporting equipments together form the weapon system. In more general use, a weapons platform could be structured around a gun, such as a gun turret on a ship, or bracing on an aircraft.
Panzerjäger
Panzerjäger (German "armour-hunters" or "anti-tank troop", abbreviated to Pz.Jg. in German) was a branch of service of the German Wehrmacht during the Second World War. It was an anti-tank arm-of-service that operated self-propelled anti-tank artillery, also named Panzerjäger. Soldiers assigned to tank hunting units wore ordinary field-gray uniforms rather than the black of the Panzer troops, while Panzerjäger vehicle crews wore the Panzer jacket in field gray.
Artillery tractor
An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres. It may be wheeled, tracked, or half-tracked. There are two main types of artillery tractors, depending on the type of traction: wheeled and tracked. Wheeled tractors are usually variations of lorries adapted for military service. Tracked tractors run on continuous track; in some cases are built on a modified tank chassis with the superstructure replaced with a compartment for the gun crew or ammunition.
Friendly fire
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy/hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire, and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage.
Mobility (military)
Mobility in military terms refers to the ability of a weapon system, combat unit or armed force to move toward a military objective. Combat forces with a higher mobility are able to move more quickly, and/or across more hostile terrain, than forces with lower mobility. Mobility is regarded as a vital component of the modern battlefield, as the ability to deliver weapon systems or combat units to their objective quickly can often mean the difference between victory and defeat.
Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.
