The Big Surprise in Gulf War I was VII Corps' secret deployment to the western Saudi desert, well past Saddam's trenches. That -- and a lot of speed and fuel and guts -- made possible the famous "left hook" which trapped most of the Iraqi Army in Kuwait.
Could this be the Big Surprise of Gulf War II? Stay tuned.
Also, I plan on wargaming this to see what effects it might have.
