In the training command, this is true, but at least in the E-6 world, we just used either a mission call sign when deployed (published on the flight schedule) or our squadron static callsign. For VQ-3 it was RAZZ, for VQ-4 it was SHADO. Never Navy XXX.
Right. I said in my post above that I was strictly talking about MY experiences, and to let the BTDT bubbas who have deployed talk about what goes on overseas.
Do you use callsigns with ATC INCONUS?
