The Main Battle Tank and Light Armour Weapon, MBT LAW, developed by Saab Bofors Dynamics, was selected in May 2002 for the UK Army Next generation Light Anti-tank Weapon (NLAW). The portable, short range, fire-and-forget system will enter service in 2006 to replace the British Army's existing Insys LAW-80 system that is reaching the end of its operational life.

The soldier can bring the missile system from the carry position to the firing position and make it ready to fire in less than 5 seconds. The soldier discards the launcher after firing and can retain the night sight if needed.

The 115/150mm calibre launcher is of composite material construction. The launcher is fitted with the gunner's optical sight, a foldaway launch device, handles and firing mechanism, battery package, carrying straps and a firing support. A mounting rail attached to the launcher is for attaching any night sight.
