There are concerns the Taliban may be seeking revenge after Prince Harry revealed he killed Taliban fighters during his helicopter missions Afghanistan.
"Take a life to save a life that's what we sort of revolve around I suppose, if the people are trying to do bad stuff to our guys, then we'll take them out of the game," Harry said.
Prince Harry's tour of duty is over.

Prince Harry on Afghan mission: 'Take a life to save a life'
Britain's Prince Harry has acknowledged that he killed Taliban insurgents on his latest tour of duty in Afghanistan as a crew member of an Apache attack helicopter.
Harry has been serving for four months as a co-pilot gunner (CPG) in southern Helmand province - considered a Taliban heartland - and flew on scores of missions with the trigger to rockets, missiles and a 30mm cannon at his fingertips.
No one is saying how many insurgents Harry might have killed but toward the end of his deployment, the 28-year-old, known to his comrades as Captain Wales, shared some of his feelings about combat with reporters while on duty in the massive military base known as Camp Bastion. He said it was sometimes justified to "take a life to save a life. That's what we revolve around, I suppose."
