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.

Never before was there a car designed exclusively for handicapped people that can only move around in a wheelchair. In the past, such people had to rely on others to drive them. Thus, it was impossible to be spontaneous and drive somewhere on a whim. Now, however, a completely revolutionary vehicle has been invented. Kenguru electric car allows for the person to roll into the back of it right on their wheelchair, strap in, and start driving. Though this vehicle might not be very fast with the maximum speed of 25 mph, it is will certainly make the lives of countless people much easier. (Photo by Kenguru.com)

The Wovel could possibly be the most advanced human snow removal machine ever created, next to simply getting someone else to do it. The revolutionary wheel design reduces the risks associated with heart attacks and back injuries because it uses adjustable leverage and your own body weight to push, lift, and throw snow up to 18" deep. The best feature about the Wovel is compared to a gas-powered snow blower, this one will always start.
