Just to note that the rebroadcast Division 3 FG is of TAC1 (Primary Tactical) it's Channel 1 on the radios.
Command 1(Command Channel) is channel 2 on the radios and broadcasted by fieldcomm on the staff chief DOITT channel.
Interesting; thanks. I had thought that the rebroadcast was configurable to whatever channel is in use at the scene; it's a fixed configuration to TAC1?
