Now we know why Harry was partying so hard in Vegas - it was a pre-deployment binge.
The randy Royal, recently photographed naked in Vegas, landed at Camp Bastion, in Afghanistan today, to begin a 3-month tour of duty as an Apache helicopter pilot.
It emerged today that William met up with Harry earlier this week to say goodbye, and that all the royal family aware he was heading to Afghanistan before it was officially announced.
“He is very proud to be given the opportunity to serve his country in the job for which he has been trained. He is going through the same range of emotions as any soldier before deployment; pride and anticipation,” a palace spokesperson said.
"His commander's assessment is that he is fully ready and trained. He will be treated exactly the same as any other pilot while he is there.
"The queen and the Prince of Wales have been kept informed all the way along and have known for a long time the window in which he would most likely deploy.”
Harry will be given ten days to acclimatise to his surroundings, after which he will start co-piloting the helicopters.
It has previously been claimed he is there to “kill insurgents”. The unit he is posted with has one of the highest 'kill rates' of any in Afghanistan.
Harry spent ten weeks in Afghanistan between 2007 and 2008 but was pulled out due to safety fears after an Australian magazine published details of his whereabouts, which was then circulated by the Drudge report.
At that time there was a media blackout on reporting his whereabouts, but this time around the Ministry of Defence has decided it is safe for people to know about Harry’s work.
It was previously feared the Taliban might target Harry if they knew where he was, meaning other soldiers could be put at risk. As the prince will be in an aircraft this time, the threat is minimal.
