A collaboration between creative director Anna Burns and the photographer Thomas Brown. Through the use of various mediums the pair have curated an exhibition that explores the masculine world of B-Movies and juxtaposed it with the traditional British landscape. Using the themes of said movies – girls, guns and explosives – and twisting it against a very British backdrop these two challenge not only the premise of each subject but also the use of their chosen medias. The duo created a wall of umbrellas displaying elements of the classic B-Movie and located them within three landscapes – one being the forest, then London’s docklands and finally the grounds of Suffolk Manor house.

Throughout the course of the long war in Afghanistan, Coalition troops have relied on thousands of military working dogs to help keep them safe, and make their jobs easier. The dogs are trained to detect explosives, to find illegal drugs, to search for missing comrades, or target enemy combatants. Not only are they active on the front lines, but behind the lines they serve as therapy dogs, service dogs, and loyal companions. They also share the same risks as the ground troops, suffering injuries and sometimes death on the battlefields. Gathered here are images of these dogs and their handlers in Afghanistan and back home, from over the past several years, part of the ongoing series here on Afghanistan.
