“MS Herald of Free Enterprise was a roll-on roll-off (RORO) car and passenger ferry owned by Townsend Thoresen. She was one of three ships commissioned by the company to operate on the Dover–Calais route across the English Channel. The ferry capsized on the night of 6 March 1987, moments after leaving the Belgian port of Zeebrugge, killing 193 passengers and crew. This was the deadliest maritime disaster involving a British ship in peacetime since the sinking of the Iolaire in 1919”. – Wikipedia

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.
