Radar
Radar detects distant objects and determines their position, velocity, and other characteristics by analysis of very high frequency radio waves reflected from their surfaces. Since the introduction of radar during the Second World War, radar countermeasures have been under development as well, and stealth technology is now an effective means of av…

Radiation Sickness
Radiation sickness is an illness caused by exposure to a high level of radiation either in a short, intense burst or gradually over a period. Symptoms of radiation sickness include vomiting, diarrhea, hemorrhaging, loss of hair and loss of energy. The main cause of radiation sickness in a military context is proximity to the detonation of a nuclea…

Radio
Radio is a communications device allowing the wireless transmission through space of audible signals encoded in electromagnetic waves in the approximate frequency range from 10 kilohertz to 300,000 megahertz.

Radioactive Decay
Radioactive decay is the decrease in the intensity of radiation from a radioactive material over a period of time. Radioactive decay is important in determining when it is safe to approach an area contaminated by radioactive material without risk of radiation sickness.

Radioactivity
Radioactivity refers to alpha and beta particles as well as gamma rays emitted from an unstable isotopes atomic nuclei. Exposure to high levels of radioactivity can lead to radiation sickness.

Remotely Piloted Vehicle (RPV)
A remotely piloted vehicle is a remotely controlled vehicle. Usually (though not always) refers to an aircraft used for reconnaissance and strike missions in regions considered to dangerous for human piloted aircraft. Remotely Piloted Vehicles (RPVs) may also be used in military exercises as moving targets to give personnel more realistic battlefi…

Rocket Propelled Grenade (RPG)
A Rocket Propelled Grenade (RPG) is a shoulder-launched, man portable weapon which is used to fire a warhead over long distances. The RPG's warhead varies, with High Explosive (HE) being most common for use against personnel and bunkers, High Explosive Anti-Tank (HEAT) used against armored vehicles, and a variety of rarer speciality types availabl…

Scatterable Mine
A scatrerable mine is designed to be laid quickly and without pattern. Scatterable mines are delivered by cluster bomb, missile, or even by hand.

Shaped Charge
A shaped charge is an explosive which has been shaped in such a way that when detonated the energy of the explosion is channeled in one direction.

Small Arms
Small arms are man portable or vehicle mounted light weapons, designed primarily for anti-personnel use. Small arms include rifles, pistols and light machine guns.

Special Forces
Special forces are highly trained and organised elite groups of soldiers, who take part in covert warfare, reconnaissance, counterterrorism and other specialised and dangerous missions.

Stealth Technology
Stealth technology is the use of special radar absorbent materials, flat angular surface design and other techniques to minimise the amount of radiation reflected to a radar installation, causing an aircraft or other vehicle to appear as a much smaller signal or not at all. Stealth technology was first used on aircraft such as the stealth bomber d…

Surface to Air Missile (SAM)
A surface to air missile is a radar or infrared guided missile that is fired from a position on the ground to intercept and destroy enemy aircraft or missiles. Also known as a SAM, surface to air missiles range in size from man portable to permanent installations around key facilities. Recent advances in stealth technology is reducing the effectiv…

Surface to Surface Missile (SSM)
A surface to surface missile is a missile launched from the ground, designed to attack a target that is also on the ground. An artillery missile.

Surveillance
Surveillance is the systematic monitoring of enemy forces using a variety of electronic and optical means as well as other intelligence assets.

Tactics
Tactics involve the positioning and timely maneuver of appropriate units to counter and destroy enemy forces on the battlefield.

Tank
A tank is a heavily armored combat vehicle designed to carry a heavy calibre cannon and machine guns on the battlefield which moves on continuous tracks to provide cross-country mobility.

Terrorism
Terrorism is the threat or actual use of violence and force by an terrorist organisation or individual terrorist against the population or property of a nation to influence the controlling power of that nation for religious, political or ideological reasons. See terrorist and terrorist organisation below.

Terrorist
A terrorist is an individual who performs acts of terrorism, either individually or as part of a terrorist organisation.

Terrorist Organisation
A terroristy organisation is an organisation that promotes and commits acts of terrorism for political, religious or ideological reasons.

Thermonuclear Weapon
A thermonuclear weapon is an advanced form of nuclear weapon in which intense heat is used to cause the fusion of atomic nuclei, which releases vast amounts of energy, causing a thermonuclear explosion.

Unmanned Aerial Vehicle (UAV)
An unmanned aerial vehicle is a remotely controlled or autonomous aircraft used for surveillance and strike missions. Known as UAV's, these aircraft are useful in situations where the it is too dangerous to use manned aircraft.

Uranium
Uranium is a toxic radioactive element, used in weapons of mass destruction such as dirty bombs or nuclear weapons.

Warhead
A warhead is the explosive, chemical, biological or nuclear device on a missile, rocket or shell.

Weapons of Mass Destruction (WMD)
Weapons of mass destruction are weapons capable of inflicting massive destruction to property and/or population, using chemical, biological or radioactive material. Weapons of Mass Destruction are also known by the abbreviation WMD.

Zone of Fire
The zone of fire is the area covered by a unit or vehicles weapons.
