The British Ministry of Defense says Prince Harry is back in Afghanistan for his second tour of duty there in four years.
The ministry said he will serve as co-pilot and gunner for an Apache attack military helicopter.
He will spend four months based at Camp Bastion in the restive Helmand Province of southern Afghanistan.
Prince Harry, known as Captain Wales in the military, looked relaxed, if slightly tired after he arrived at Camp Bastion.
The 27-year-old third in line to the throne hit the headlines last month after he was photographed nude during a wild week of partying in Las Vegas.
The prince had made no secret of his desire to return to serve in Afghanistan.
His previous secret deployment in 2007 had to be cut short after media reported on it .
