Also coming are unmanned ground vehicles (UGVs).
But such ground vehicles remain few and far between.
The assets include ground equipment and ground vehicles.
The military is not completely bereft of high-tech ground vehicles that can assist in warfare.
West Germany mobilised helicopters and ground vehicles to help to clear up any contamination.
But the Army might have to revise its plans for eight types of new ground vehicles.
"We would be forced to buy fewer ships, planes, ground vehicles, satellites and other weapons," Mr. Hagel wrote.
The Army also bought 4,000 Stryker ground vehicles, 2,000 more than intended, and more than 15,000 mine-resistant trucks.
"The hard problem in building autonomous ground vehicles is that the ground is hard," said Gill Pratt, a program manager at Darpa.
"The technology we are testing on the FED Bravo could potentially be integrated into future military ground vehicles," Mr. Huffman said.
Engineer Ordnance Disposal (EOD) experts disable or destroy IEDs through a variety of means, including the use of robotic ground vehicles and explosives.
