The RNZAF envisaged that these F16s would be for regional high-ish intensity wars and would operate in cooperation with RAAF F/A 18A+ squadron/s with the RAAF Hornets taking care of the Air to Air task and the RNZAF F16s undertaking ground attack tasks using their B-model Mavericks and 500lb LGBs.
The Challenge is to invent a plausible post 2002 scenario where an ANZAC wing of full-sized* RAAF Hornet and RNZAF F16 squadrons operate together in the above roles; RAAF A2A and RNZAF A2G.
Clarification: the RAAF Hornets can also attack ground targets, but it must be after the A2A task is sorted.
*The Hornet Sqn the RAAF sent to Iraq in 2003 had 14 aircraft, but more recently sqns have been 6-8 aircraft which is barely enough for 2 'flight' sized sorties a day.
