SA80 is the designation for a revolutionary family of assault weapons. On its introduction, it proved so accurate that the Army marksmanship tests had to be redesigned.

SA80 A2 comprises the Individual Weapon (IW) and the Light Support Weapon (LSW).

These are the British Army's standard combat weapons. Made by Heckler and Koch, they fire NATO standard 5.56 x 45mm ammunition.

Both weapons have been modified in light of operational experience. A major mid-life update in 2002 resulted in the SA80A2 series - the most reliable weapons of their type in the world. This reliability is combined with accuracy, versatility and ergonomic design. It is considered a first-class weapon system and world leader in small arms.
