He seems a bit extreme. Is any of it true? ie: wheeled off-road becomes more likely to become stuck than tracks? I imagine that it has more to do with the weight of the vehicle. I love the picture of the 113's coming to the rescue!
I have heard that the Stryker with SLAT armor is much heavier that it was supposed to be, and that it is top-heavy, as well. But I can not imagine that an old APC would fair any better.
