In HRH Harry's defence, it isn't his decision and he was probably raring to go. He's probably as p*ssed off not to be going as those who threatened are that he won't be their target. After all, back when his uncle was at war, the Argentines played more or less by the rules of "civilised" war and so did the UK forces. They would have been happy to have shot him down or sunk his ship, but they wore uniforms while attempting to do so.
For everyone else in a mobile grade, hey, I know it sucks big time when you have family settled and friends in one area and are forced to move. But if you can't take a joke.....
