Neat Idea, any idea the price tag? I think it expensive (and I bet it is) it would be useless for military purposes. I say this for a couple of reasons.
1) Fuel- A mule or donkey can do the same thing and they are much cheaper to fuel, and in a pinch they aren't bad eating.
2) The price tag is high and I bet it's over $10,000 per unit, an emp will kill it as easily as a 308 round. Pack mule is cheaper.
3) It gives off an electronic and heat signature.
I think they should build something like these for military vets that have lost their legs. But that won't happen since very few care about the disabled vets.
