Prince Harry has been promoted to captain after completing five years' service as an officer in the British Army.
The announcement by St James's Palace comes a few days after the royal, a trainee Apache helicopter pilot, passed the half-decade milestone.
Following a 44-week training course at Sandhurst, the prince was commissioned as an Army officer on April 12, 2006. As a non-graduate he was eligible for promotion to the rank of captain after five years.
A St James's Palace spokesman said the former lieutenant would now be known as Captain Harry Wales.
He added: "Prince Harry has been promoted to captain within the Army Air Corps in recognition of time service in the Armed Forces."
As a captain he will be on a pay band of £37,916 to just over £45,000.
The prince has been forging ahead with his military career and is well on the way to realising his dream of returning to the front line in Afghanistan.
Harry's official office also confirmed that the prince had passed an eight-month "conversion to type" course to learn how to fly the Apache helicopter while at the Army Aviation Centre (AAC) at Middle Wallop, Hants.
Before his brother Prince William marries fiancee Kate Middleton on April 29 the royal will begin the final phase of his training at Wattisham Airfield in Suffolk, and spend time in America under instruction.
Speaking earlier this month while training for an Arctic expedition, the royal said it would be pointless to undertake such costly training if he never went into combat. "I'd just be taking up a spare place for somebody else if they didn't have me going out on the job," he said.
