'Military’s RFID Tracking of Guns May Endanger Troops'

Reports that the military has started outfitting firearms with RFID tags for tracking have raised security alarms, according to Threat Post.

The Department of Defense, the Marines and the Navy have already rejected the RFID tagging tech for that specific reason. With the right equipment. you could read an active RFID tag from a couple of hundred meters away without much problem.

However, five Air Force bases are operating at least one RFID armory, along with a Florida-based Green Beret unit that uses RFID in just a 'few' armories.
