Interesting videos, Tom. The Russians seem to have the market cornered in the off-road truck and tractor department. They're pretty good at driving them, too. Aside from maybe some kind of specialized mining/industrial vehicles, American trucks and tractors don't even come close to what the Russian makes are obviously capable of. I've never even encountered a wheeled US military vehicle that could do those kinds of things.
The American versions of the yellow articulated 4WD tractor would have climate control, cruise control, a seat like Kirk's on the Enterprise and GPS-guided steering. No way they could deal with those conditions but I guess that's not what they're designed for.
They need to send the IRT boys over there and let them get in on some of that action.
