Bob C, lets face it, journos aren't stupid. You can't really hide the unit that he's serving with, someone will find out. Then announcement that said unit deploys to iraq.... 2+2=4 and young harry isn't to be found anywhere abouts... Not exactly rocket science!
(BTW to all those that slate him for being found making a fool of himself in clubs/pubs/bars, he's significantly better behaved than most of the country's youth today, so don't knock it!)
