2–8. Carrying concealed firearms
a. Military or civilian personnel may carry concealed firearms
while performing law enforcement or security duties if carrying
firearms openly would compromise the mission.
b. Personnel authorized to carry concealed firearms will possess
documentation identifying their law enforcement or security duty
status and authorization to carry a concealed firearm. During covert
operations, field grade commanders or provost marshals may waive
the requirement to carry identifying documentation if such could
compromise the mission or endanger the person carrying the
weapon (requires sufficient control over operations to ensure that
authorization and identification can be readily verified if required).
A waiver under such situations does not preclude the requirement
for written authorization to carry a firearm.
