Admiral Flota Sovetskovo Soyuza Kuznetsov (Russian: Адмирал флота Советского Союза Кузнецов “Fleet Admiral of the Soviet Union Kuznetsov”), originally named Riga, renamed Leonid Brezhnev then Tbilisi) is an aircraft cruiser (heavy aircraft carrying missile cruiser (TAVKR) in Russian classification) serving as the flagship of the Russian Navy. She was originally commissioned in the Soviet Navy, and was intended to be the lead ship of her class, but the only other ship of her class, Varyag, was never commissioned and was sold to the People's Republic of China by Ukraine under the condition she would never be refitted for combat. Kuznetsov was named after the Admiral of the Fleet of the Soviet Union Nikolai Gerasimovich Kuznetsov.

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.
