Soldiers gradually navigate a Heavy Expanded Mobility Tactical Truck, better known as a HEMTT, through an obstacle on the new Driver's Training complex at the Grafenwoehr Training Area in Germany. The complex is spread over a 7.6 km area, and consists of a sequence of eleven obstacles designed to train soldiers in a variety of U.S. and multi-national military vehicles, from the smaller more versatile Humvee to U.S. and NATO European model vehicles and tanks. Each of the eleven obstacles replicates the dangers and challenges soldiers, Marines and airmen encounter when driving in diverse battlefield environments.
