It begs the question as to where the ADF has come with RW support to the troops in the 40 years since Vietnam. Much water, bitter water, has passed under the bridge, in an effort to provide empathetic support to the chaps on the line.
In 1989, 9SQN became A SQN of the 5th Aviation Regt and 35SQN became B SQN of the 5th. Moving RW from RAAF to Army was supposed to markedly improve the level of support.
Army now operates 35 Blackhawks, 6 Chinooks, plus MRH90 plus Tiger, plus ancilliaries. From that fleet, they field two CH47 in Afghanistan.
My observation is that 40 years of lessons learned, including the 20 years of integrated Army RW doesn't seem to have done much for the level of fielded air mobility support for the troops.
