Army CI Discussion Group
The Army Counterintelligence Discussion Group (ACIDG)
mailing list is open to all active, reserve, former, and retired
Army Counterintelligence Special Agents who held the MOS 97B,
351B, 35E, 36A or GS-0132 civilians who are graduates of the US
Army CI Special Agent Course.
ACIDG was founded in 1998 before S2_Online list
server/discussion group. The USMC CI Asso list was apx 3 years
before ACIDG. Both of these list success was what spawned
S2_Online list server.
Subscribing is easy, if you qualify, and you can
