IRAQ 2003 :-
Reports indicate that the No. 75 Squadron's activities were somewhat restricted in their military role compared to similarly equipped US forces. Australian aircraft were not permitted to operate in the "Baghdad SuperMEZ" (Missile Exclusion Zone) because of fears that the Hornet's electronic warfare systems were inadequate, though the report indicates that they were identical to American Hornets operating in this area. Furthermore, they were not permitted to conduct close air support missions in urban areas because of fears of collateral damage. These restrictions were in line with the rules of engagement set by the Australian Government, which were reportedly more restrictive than the rules governing the conduct of British and American forces.
Due to the more restrictive ROE and risk level imposed on them, I believe they came home early.
This isn't about having a 'go' at the fast jet guys, we were similarly limited, but could provide other assistance. If fast jets can't drop bombs, they are limited to shows of strength, as was the case in the latter part of the campaign.
