Those of us who have ridden the roads know the shortcomings that the hummer has. I don't know why we are even arguing this thread. In August we had three troops killed by a pressure activated IED that went off under their hummer. The gunner was thrown free and is alive today. The flat bottom of the hummer didn't allow any of the force of the explosion to be "vented" away from the crew. Maybe they still would have died, but the South African vehicle would have improved their survivability.
thats what i was refering to when i said varient. pick whatever one you want and start sending those and move the Humvees to the rear. :)
