The Mectron MSS-1.2 is a Brazilian personal missile launch system with laser guidance used for close-range fighting. It is the standard personal missile launch system of the Brazilian army and marine corps. The MSS 1.2 has a range of 500 to 3,000 m and can be used against tanks, armoured vehicles, infantry, bunkers, small buildings, boats, aircraft, and helicopters.

The missile is equipped with a warhead type hollow charge and a two-stage propulsion system. Guidance is performed by a laser beam projected by the fire control system. Similar in performance to the Russian 9M123 Khrizantema, it is meant to compete with other next generation missiles. The MSS-1.2 was designed to deal with current and future armored threats such as Russian T-90, American M-1 Abrams and British Challenger 2 tanks, but can also be used against low-altitude aircraft such as helicopters and unmanned aerial vehicles. It has successfully breached more than six meters of concrete in tests carried out by the Brazilian army.


The anti-tank missile MSS 1.2 is in production, waiting for placement in the Brazilian Army. Although the requirement of EB was for a missile with a 2,000 meter range, during recent tests the missile remained "attitude of target", (i.e., it was guided and impacted on the target at ranges ranging from 3,500 to 4,000 meters) "We put a conservative in the serial range of 3000m. But it goes much further, and accurately, while maintaining full control."[1]
