Humvees were GREAT in the woods. small trees were no problem. However, most of the time, I had to drive them on the road (National Guard weekend duty), and they were loud and uncomfortable.
Not much fun in the snow, either. The Humvee wasn't as bad about rolling over as the old Ford M151 series *roly-Poly* jeeps were, but when a 151 flipped, three or four guys could usually turn it back over. Not so with a Humvee, and it looks like this thing won't be any better- and it's got a high center of gravity too.
Of course it's not amphibious. When we come to a blue line on a map, that's where we stop to wait for the helicopter lift across.
Looks like a great little companion piece for the Stynker [officially, Stryker]
