Sounds like something out of the old Stev Jackson game "Car Wars."
I’m not familiar with the reference, but look what happened to the hummve. It was never intended to carry all that armor, and from what I have heard from returning GIs it is top heavy and slow. Truckers prefer the 5 ton guntruck for convoy security. It’s faster and far more stable. I heard of a new terrorist tactic yesterday. They will spray oil on a curve or traffic circle. When the Hummve hits it it will skid and flip. The terrorists then open up on the rescue team when they dismount.
It doesn't work with the 5 ton.
