The Main Battle Tank and Light Anti-tank Weapon (MBT LAW), also known as the NLAW, is a joint British and Swedish short-range fire-and-forget anti-tank missile system. Designed for use by infantry, the MBT LAW is shoulder fired and disposable, firing once before being disposed of. It is currently in use with the military forces of the United Kingdom, Finland, Luxembourg, and Sweden. Using NLAW an individual soldier has the ability to take out any heavily-protected armoured vehicle, including a main battle tank, with a single shot. It is a shoulder-launched, anti-tank missile system that attacks the target from above. This makes it the most effective anti-tank weapon for dismounted light forces operating in any environment, including built-up areas. Originally developed for Sweden and Great Britain, it meets all requirements for a modern anti-tank weapon system for use during international operations as well as for national defence.
