DOD has awarded a contract Tuesday for more than 2,200 lighter versions of MRAP vehicles for Afghanistan.

MRAPs have proven to withstand blasts from roadside bombs better than Humvees, but Afghanistan lacks Iraq’s road network, limiting where the vehicles can go.

The MRAP All-Terrain Vehicles are meant to be light enough to go off-roading while maintaining MRAP vehicles’ V-shaped hull that provides protection from blasts from underneath.

The vehicles will begin to be fielded by the end of this year.
