The M1135 Stryker NBC RV provides NBC situational awareness to increase the combat power of the BCT. The core of the NBC RV is its on-board integrated NBC sensor suite and integrated meteorological system. It’s an NBC positive overpressure system that minimizes cross-contamination of samples and detection instruments, provides crew protection, and allows extended operations at MOPP 0. M1135 replaces the M93 Fox vehicle.
