The LAW 80 (Light Anti-armour Weapon 80), regularly referred to as LAW 94 in British service, is a man-portable, disposable

anti-tank Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first dev ...

To launch the rocket the firer removes the large protective end caps and extends the rear of the launch tube, opens the sight, and moves the arming lever to "armed". The weapon is then in spotting rifle mode. To fire the rocket, the firer moves a charge lever forward with his firing hand thumb. The
