The M21 RSCAAL is a two-man portable, automatic scanning passive infrared sensor which detects nerve and blister agent vapor clouds based on changes in the infrared energy emitted from remote objects, or from a cloud formed by the agent. The M21 RSCAAL is a stand-alone tripod mounted, chemical agent over-watch system. It consists of a detector, tripod, - transit case, power cable assembly, and standard military power source, capable of scanning horizontally 60 degrees. It will be used for reconnaissance and surveillance missions to monitor avenues of approach and egress, bridges, road junctions, and other point targets to search areas between friendly and enemy forces for chemical agent vapors, and to provide advanced detection and warning of chemical hazards. Where possible, the M21 RSCAAL will be employed in pairs (2 reconnaissance teams) so that one M21 RSCAAL can be used in an overwatch position when the other reconnaissance team is moving.
The Venom is a 40 mm, multi-shot, electrically actuated, non-lethal munitions grenade launcher mounted to the High Mobility Multi-purpose Wheeled Vehicle (HMMWV) turret blast shield. The Venom system consists of 3 banks of 10 launch tubes, each at fixed angles of 10° , 20° , and 30° from the horizontal, achieving 360° coverage by traversing the HMMWV turret. The Non-Lethal/Tube Launched Munitions System fires a multi-flash-bang grenade out to ranges beyond 100m. The system is comprised of three subsystems: launcher, firing circuit, and ammunition. Venom will provide Marine Forces the ability to deliver a high volume of non-lethal fire at range, both day and night, enhancing convoy security operations. Venom will enable Marines to deter and dissuade errant vehicle operators from encroaching into security zones by helping to determine intent and increasing standoff distance and reaction time in responding to threats.
