The most exciting military vehicles of 2017

The aim is for a SMET robot to be able to carry 1,000 pounds across more than 60 miles in 72 hours. Whether you're interested in trucks, tanks, motorcycles, armored vehicles or ATVs, 2017 was a great year, with lots of incredible machines. And it was a year in which lots of out-of-the-box advances – some might even say shocking – were revealed. Where do we find these insider machines? I also meet with military and private sector innovators to closely evaluate the vehicles and put them through their paces. In the eye-popping category, it will be hard to surpass the military's announcement that they've figured out how to use urine as fuel for vehicles in war zones.
