It'd be a blast as a recreation vehicle.
I think it's limited as a military, it is limited.
They sure seem to stick to the trail in that video. A bike could do that and more with one that has good clearance.
The remote control is probably the best feature.
Lot's of questions too - I'm sure they have the answers already.
what is the range?
How do you recharge/refuel in the field?
How heavy is it if you have to "portage" it?
How much can it really tow - was that dummy in the trailer a life-like weight?
Can you mange it hands free so that you can fire a weapon while moving? Otherwise, you're a duck in the carnival shooting range.
