Despite all the jokes and stuff it's actually an interesting question.
I guess the answer is that knowing he's in a helicopter doesn't change anything. As someone said, the taleban are already doing their level best to shoot down any helicopters they see, so knowing Harry's in one doesn't make any difference.
However, knowing that he was on the ground somewhere could change their strategy in such a way that it it may endanger the people around him to a greater extent than they already were.
i don't think the reason he is out there is because of any shenanigans before, he is a serving soldier, and if his commanding officer thought it would be too dangerous he wouldn't be there. As to someone who has no time for the Royal Family, well that is your prerogative, but as been pointed out many of them have served their country in the armed forces, have you?
// I wish the press would leave him alone//
I second that Boxie, the press seem to be hounding him just like they did to his mother. As for the "naked" stunt, it was on the internet and apparently he wasn't completely naked just covering his "crown jewels" with cupped hands!! No different to WI calendar girls then in their poses ................... :))
