hmmm only 3 DGOs per group... probly still too many i reckon, heard Tatiara DGO5 on the scanner the other day, now thats ridicoulous, having at least 6 group officers, not sure if there were more lol...
anyway, we run with 1, 4, 4 and suringthe day we are lucky to get one of them, fortunately for us though we have a couple of FFs that actually have there stuff together and know what the go is, these guys are regular responders and are often in charge of the appliance...
the 1, 4, 4 system works well and really i see no need for any more officers or SFFs, although your system at TTG does sound like it had its advantages...
I see the position of SFF as the learning grounds for the up and coming looies, people that are likely to be wearing a yellow helmet in the next 5-8 years....
