I came up with this idea a couple of months ago but only really considered it now. Basically the deal is that RAAF fixed and rotary-wing personnel patrol the skies for hostile activity with F/A-181s and helicopters of sorts while Airfield Defence Guards (infantry, basically) patrol around rebel-infested areas in armoured vehicles with air support. Since I haven't the slightest flippin' clue where to link a group for those who may be interested, here you go.

Staff members, if advertising is not permitted here let me know and I will remove the post (or you could do it on your own... one of the two)
