They're not the only ones who destroy UAVs.

From the Daily Mail 22 April...
An RAF bomber deliberately destroyed a £10million British spy plane to prevent terrorists accessing its secrets.
The unmanned surveillance system, the Reaper UAV, crash landed in Afghanistan during a covert operation. Special forces were dropped in to the crash site by helicopter to recover the plane's top secret data - believed to include a high-intensity camera and computer memory chips.
An RAF Harrier jet was then scrambled to blow up the stricken aircraft using a laser-guided bomb in a bid to stop the Taliban from discovering its sensitive data.
