Soldiers assigned to the 95th Chemical Company, “Arctic Dragons”, 17th Combat Sustainment Support Battalion, U.S. Army Alaska, begin a gunnery live-fire exercise with M1135 Stryker Nuclear Biological Chemical Reconnaissance Vehicles on Joint Base Elmendorf-Richardson, Alaska, April 5, 2017. The gunnery tested Soldier’s proficiency with identifying, engaging, and eliminating hostile targets while increasing combat effectiveness. The Styker NBCRV provides Nuclear, Biological, and Chemical detection and surveillance for battlefield visualization, and situational awareness to increase unit combat power. The core of the NBCRV is its on-board integrated NBC sensor suite, and integrated meteorological system. An NBC positive overpressure system minimizes cross-contamination of samples and detection instruments, provides crew protection, and allows extended operation at Mission Oriented Protective Posture.
