The ARH Tiger was more than ready and should have gone to support ADF soldiers. You will hear all kinds of bleating and excuses as to "sustainability", training gaps etc
My response is "grow a set of balls!" The hierarchy were unwilling to take the risk for their careers and their mindset of "how many people" was way too many!
The French took theirs (a less capable version) to Afghanistan, Libya and Mali, the Australian Army took theirs to Shoalwater bay.
The drivers, maintainers and ops support were/are more than capable. The commanders were more worried about their pay checks for Fifi and Crispin's private school fees and getting their next promotion or a job with the manufacturer or an affiliate.
The Tiger is an incredible capable aircraft. It is robust, reliable and somewhat worrying for the bad guys. It is such a shame that the risk to Australian soldiers was increased as a result of them not having the required level of organic aviation support in theatre.
