What is this?
ROMEO = Regular Patrol
OMEGA = Supervisor (Sergeant+)
BOY = Ranger
ALPHA = Special Enforcement Bureau
BOBBY = Canine Unit
DUKE = Air Support
IDA = Biker Unit
I dont mean to sound like a dick, but I think you need to revise your topic. Clarify a bit more what your group is about and all that.
Furthermore, the callsigns and names seem to have been ripped from another server. I suggest that you make your own because nothing beats a unique idea. I say this because I know for a fact that the Omega callsign being the Supervisor (Sergeant+) is only used in that server. Not IRL not anywhere else.
Anyway, here's a bunch of callsigns for you I made:
ROMEO -
Regular Patrol.
SIERRA -
Supervisor Unit.
ROMEO BOY -
Regular Rancher.
CHARLIE -
Canine Unit.
ALPHA -
Air Support.
BRAVO -
Bike Unit.
TANGO -
Tactical Response Team (Special Enforcement Bureau? )
This now, at least makes sense. Also a tip, just keep it to Romeos and supervisors for now. :P
