Sangin in Helmand Province is a central location for Afghanistan's opium trade and has traditionally harboured criminal and extremist elements. For UK troops it has a reputation as the most dangerous place in Afghanistan.
Despite just a tenth of British forces being deployed there, half of UK casualties occur in Sangin and half of IEDs encountered are found in the area.
Of note is the number of British fatalities which have been the result of gunshot wounds rather than IEDs. This is due to a change in tactics which has seen troops getting closer to the people.
Increasing the number of security posts in the centre of Sangin town has brought relative calm to the bazaar.
But many troops are based in forward operating bases (Fobs) and patrol bases (PBs) outside of the town, where there is frequent violence.
Travelling out to Patrol Base Blenheim, on the violent fringes of north-east Sangin, involves a trip in a Panther vehicle (centre) flanked by two Jackals (left and right).
Patrolling these areas is a dangerous business. These are soldiers from 4 Rifles based at PB Blenheim, one of the most insecure places in Sangin.
But there are opportunities to relax when not out on patrol.
The soldiers at one of the Fobs have had some fun calculating just how far from home they are.
And some British soldiers have adopted local dogs as pets. They get their families to send them dog food so they can feed the animals.
