M93A1 Fox Nuclear, Biological, Chemical Reconnassaince Vehicle

The M93A1 Fox is a chemical, biological, radiological and nuclear (CBRN) reconnaissance vehicle used by the U.S. Army. The vehicle can detect, identify and mark the areas of nuclear and chemical contamination. It can take samples of soil, water and vegetation to provide accurate information to commanders.

The mission of Fox NBCRS is to detect, identify, mark, sample, and report chemical and radiological contamination on the battlefield. It is basically a rolling laboratory that takes air, water, and ground samples and immediately analyzes them for signs of weapons of mass destruction.

NBC defense encompasses three major functions:

  • contamination avoidance
  • protection
  • decontamination

The crew accomplishes these missions by using a sophisticated suite of nuclear and chemical alarms and detectors that have been integrated within the vehicle chassis. One of these detectors, the M21 Remote Sensing Chemical Agent Alarm allows the crew to detect chemical agent clouds as far as 5 kilometers away. The crew can perform all these reconnaissance operations while operating in a shirt-sleeve environment inside the vehicle, even while the vehicle is operating in a contaminated area.
