The U.S. Army is giving away 13,000 armored trucks, worth about $500,000 each. The 20-ton MRAPs, or Mine-Resistant Ambush-Protected trucks, were built specifically to save U.S. soldiers from roadside bombs in the Iraq and Afghanistan wars. Now the trucks are patrolling U.S. city streets. U.S. law enforcement agencies have received the lion’s share of this high-powered military surplus.
