The Bundeswehr plans to install the Rapid Obscuring SYstem (ROSY) rapid smoke dispenser on up to 500 vehicles or vehicle weapons stations, Rheinmetall announced on the second day of its 3rd Infantry Days symposium held at the company's Unterluess site on 24-25 April.
Even when moving, a vehicle equipped with ROSY can fire 40 mm rounds to lay smoke 360 degrees around it in the line of sight of small and medium-caliber direct fire weapons like anti-tank guided missiles and rocket propelled grenades in less than 0.5 seconds. The smoke blocks the line of sight of laser designators, beam riders and range finders, as well as night vision equipment and infrared trackers.
ROSY reacts automatically via laser or acoustic sensor triggering. It consists of one to three launcher units with one to three magazines with five launcher units each. In non-lethal applications like riot control, it can fire CS gas or flash bang ammunition. It can also fire training munition.
Other countries have expressed interest in ROSY, for example the Netherlands, whose special forces have trialed the system on Mercedes Benz and Landrover Defender vehicles (see YouTube link).
At Infantry Days, ROSY was demonstrated on a small unarmored vehicle which looks like a Smart car designed to move special forces quickly from point to point.
Peru is the only other country to have ordered ROSY, in its naval version for six of its Griffon GH-2000 TD(M) hovercraft to protect them during counternarcotics operations in the Amazon region.
