Mack Trucks Inc., Allentown, Pa., has worked with the U.S. Army and Force Protection to develop the Buffalo blast-resistant vehicle. Features include a 23-foot long robotic arm to detect and disable improvised explosive devices, or IEDs—munitions packed into piles of concrete, trash bags, or roadkill along roadsides, triggered when vehicles pass.

The first 10 Buffalo vehicles were produced in 2003; since then, dozens more have been ordered for shipment to the Middle East. Mack provides the chassis, including all drivetrain components; Force Protection assembles the final vehicle using special armor shaped to exact blast-deflecting angles. The Buffalo is 12 feet high, 28 feet long, and weighs 21 tons.
