 British troops board a  RAF C-17 as they leave Afghanistan to go home at Kandahar airfield on November 13, 2014 in Kandahar, Afghanistan. Now that British combat operations have ended and the last UK base in Afghanistan had been handed over to the control of Afghan security forces, any remaining troops are leaving the country via Kandahar. As the drawdown of the US-led coalition troops heads into its final stages, many parts of Kandahar airfield - once home to tens of thousands of soldiers and contractors - are being closed or handed over to the Afghans.
