Prince Harry is reported to have killed a Taliban commander in Afghanistan, although the incident is being disputed.
The Sun newspaper is reporting the 28-year-old prince, a gunship co-pilot, fired a missile that eliminated a senior terror leader.
"We were on patrol and the Apache helicopters were called in. We heard this posh voice come over the radio and knew it was Big H (Harry's nickname). They were tracking a Taliban leader - he was commander level," a "defence insider" said.
"The Apache then let off some Hellfire missiles and its 30mm cannon and 'boom'. It was Big H all the way."
Gunship co-pilot Harry is on tour in Helmand and flying daily combat missions helping "troops in contact" - ground forces engaged by enemy fighters.
"Big H is a legend, he's been out in Afghan and he's doing the business. All the guys love him - he's Big H."
According to The Telegraph, defence sources denied the prince had killed a Taliban "commander" but admitted he had deployed weaponry on operations.
The sources disputed the incident reported in The Sun, and the nickname, but did not deny that Harry had killed Taliban fighters.
The Prince, known as Captain Wales, was expected to join fellow officers on Christmas Day, serving up food for his men.
A spokesman for the Ministry of Defence said it did not comment on individual deployments.
The prince is near the end of a four-month tour of duty based at Camp Bastion in Helmand Province.
