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.

Do you think that history is a science? Well, not exactly. First, and foremost, history is the state's “legend of wars”, it’s official regalia. Of course, public historians are not interested in scientific truth – quite the opposite. In this respect, any attempt to present a state’s history as altruistic and benevolent as possible is welcomed and encouraged – as opposed to any revisionism attempts that may be more accurate. In this matter, Chinese have surpassed us all – they revised in highly creative manner (but rather shamelessly) the technology already invented by Europeans, a process that resulted in oldest state on the planet. Here is an interesting paradox: ask any sinologist about the Middle Kingdom during second century B.C., and he will describe it to you in such a vivid manner as if he has been living there all his life – but as soon as you will ask him to describe Chinese history in the 19-20th centuries… let's say, his eagerness will be greatly diminished. However, we will discuss China in a different article, and in the meantime we will try to understand how exactly historic “legend of wars” is formed and functions – based on a specific and well-known example. A great example is Ferdinand Magellan's first voyage around the world.
