i beg your pardon?
christ knows where you got that picture from, but they are new helicopters you're looking at, Tigers fresh off the boat from the US. god knows whoes horses they are, probably ran onto the airfield with the wild man eating kangaroos!
funny you should say 'look down under and sigh', because i'm a member on the US Army forums (with the same call sign), and on there the US guys bag the heck out of the Canadian forces.
on another note, there is no such thing as an Australian Air Cavalry Regiment, no doubt that photo was taken during ceremony. Unfortunately the ceremonies are very British in nature... a shame
