I served as an Infantry officer in the Battalions during and after the switch of rotary wing assets to the Army.
The Air Force seemed to have little understanding of an Infantry units operational needs. They were not readily available and didnt seem particularly interested in staging close to where they were needed. Their participation in air assault appeared to lack any tactical sense, or vigor. Straight and level at 1000 feet, then back to the officers mess or hotel.
The Army Aviation pilots at the time had all been through Duntroon, either solely or after ADFA. They had excellent tactical sense and knew what the Commander needed. They also understood how long it takes to walk 1 kilometer in primary jungle with 40kg on your back ........ After being dropped in the wrong place
Ask the customer who they'd want providing fire support from a Tiger. I think you'll find the answer is Army Aviation.
