For the first time, Prince Harry has reportedly killed a Taliban chief in Afghanistan. The Royal Prince, who is an Apache pilot, released a missile strike to eradicate the terrorist leader in the late of October.

"Big H is a legend. 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. They were tracking a Taliban leader. He was commander level," an insider told The Sun.

The 28-year-old Apache pilot is responsible in maneuvering the aircraft and controlling the weapons. "The Apache then let off some Hellfire missiles and its 30mm cannon and 'boom'. It was Big H all the way," the insider further shared.

Prince Harry is currently assigned in Helmand, Afghanistan. He has been flying daily combat missions aiding "troops in contact," a code given when ground forces are occupied with enemy fighters.

Prince Harry was able to develop a close companionship in Helmand where his comrades gave him the moniker "Big H." "He's like a normal squaddie. All the guys in Afghan have so much respect for him and love him. 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. He likes a drink and a laugh and he's one of the lads," the source told The Sun.

Prince Harry's bravery still puts his life at risk which made his father, Prince Charles, express his anxiety for the safety of his son. "The younger one is at this moment in Afghanistan. Fortunately, he rings me every now and then," Prince Charles recently told The Sun's Military Awards.

Despite his worry, the 64-year-old Prince Charles still understands and supports the military duties of Prince Harry. "I really do understand the worry of service families when their loved ones are away serving in somewhere like Afghanistan. It's almost easier for those serving away than for those left behind because you worry all the time," Prince Charles stated.

"So I do appreciate the extraordinary resilience and the unbelievable support provided by the families back here who encourage and remind their loved ones that they are there for them, despite what they have to put up with," Prince Charles further added.

Prince Harry's recent tour of duty in Helmand is already his second military mission. Unknown to the public, he has served 77 days on the front line from 2007 to 2008 before shifting to choppers.

After passing the difficult Apache flier's course in 2011, Prince Harry was deployed on a mission in September. After 18 months of meticulous training, Prince Harry was hailed as the Top Gun pilot in his class last February.
