Since September 1 1,200 1, the Department of Energy has, on several occasions, revised
its security posture based on identified threats and adversaries. These revisions in
security posture have driven Departmental sites to upgrade their defensive and tactical
equipment. Subsequent changes in the perceived threats have, in some cases, led to a
reduction in the need for certain types of weapons, thus creating a pool of surplus
equipment. These surplus weapons could potentially be used by other Department sites
and Federal law enforcement agencies.
