DOD Fort Meade Unknown Talkgroups

I've been hearing a lot of activity on the DOD system out of Fort Meade. Sounds likes talk around for the military police or the gate guards.

They aren't talkgroups - they are "iCalls" / "private calls" (user radio to user radio vs. user to group)

i means ICall and the rest is the radio ID of the user

Basically like simplex?

They still go through the system/repeaters but instead of the conversation being on a "group" where all users on that group can hear and respond, it's radio to radio - so only the two users hear each other.

Those are probably NSA PD going by the radio IDs listed. Ft Meade MP units are usually 700xxx series
