All in all, I think the whole thing comes down to this - feces occurs. Given the number of hours these vehicles have been driven and the various dumps they've been driven in/through, I'd say the what, 6 major accidents that have happened is pretty damn good. I've both ridden in the back of the LAV III's with 2 RCR and crew commanded a Bison Amb for a couple of years. I thought the LAV's were the cat's backside. The Bison too is great. One little thing though - if ground is unstable underneath them and it gives away, DUH, it'll roll, it's basic physics. I've had to quickly rehearse the emergency decapitation avoidance drill a couple of times in the Bison when some crap ground threatened to give way underneath me. The vehicles have a fairly high centre of gravity, long narrow wheel bases are a little top heavy (LAV, Coyotes, Cougars, etc) and are therefore a little unstable. Doesn't mean we should panic about it, just drive around the situation. I notice they aren't freaking out about all the MLVW rollovers that have happened over the years (they suffer the same thing), Leopards, M113's and variants. The one thing I remember a big stink about was in the early 80's when a young reservist rolled a Jeep with a 106mm trailer on it and was killed - that had alot of backlash in the press for awhile. Mind you, I've seen lots of Jeeps roll over - '54 patterns, CJ and YJ's as well. Alot of it came back to people just not driving them the way they were meant to be driven.
Yeah, I know, sum up - in the end this will likely come out as a combination of some really rapid reflexes, rapid overcompensation and dumb luck (that's what I hope anyways). As long as it goes into everyone's lessons learned basket, hopefully we won't be having a repeat of this.
