Heavy Expanded Mobility Tactical Truck
The HEMTT's objective is to provide heavy transport capabilities for
supply and re-supply of combat vehicles and weapons systems for the United States Army. It is distinguished by extreme mobility compared to standard 5-ton trucks,
thanks to its large number of wheels and turbo-charged engine, combined
with all-wheel drive and very large, low-pressure tires. Though far
less publicized than the Humvee, it has been extremely important in transporting logistics behind quick-moving forces based on the M1 Abrams tank.
