Chinook helicopter crews based at RAF Odiham in Hampshire have been playing a vital role in the conflict in Afghanistan.
The crews spend 10 weeks nearly 4,000 miles (6,400km) from home based at Camp Bastion working in tough conditions with temperatures of over 40C (104F).
The BBC travelled to Afghanistan to see how they work.
