Instapundit is reporting that the new uparmored Hummers are having rollover problems in Iraq. At times the drivers will survive the ambush only to flip on the high-speed getaway.
Now this will come as no surprise to offroaders who don't particularly like the Humvee. Long story short, the hummer has a fully independent suspension on it instead of more traditional solid axles. This suspension is notorious for having rollover problems, because the wheels can tuck in under the car if they get off the ground. The hummers saving grace was its large size and low center of gravity that made rolling unlikely. Unfortunately uparmoring has significantly raised the CoG and now this is no longer true.
I would just like take the opportunity to point out that we have a ton of M113 Gavins in Kuwait. Perhaps instead of trying to turn hummers into the Armored Personnel Carriers that they aren't, we could just use honest-to-God APCs in the first place.
