Here are quotes from Hackworths January 21, 1991 Newsweek cover story article:
Casualties wont be 200 Americans dead a week, as in Vietnam. They will be more than 200 dead an hour in the first round.
The aircraft arranged in the Gulf are the wrong mix of aircraft
The Iraqis should give a good account of themselves in air attacks.
The Abrams M-1A1 tank is a fuel guzzler and a real liability in a roadless terrain
For the most part, from rifleman to battalion commander, these dedicated (American) soldiers and Marines have never seen war. And in my judgment they havent yet been made hard enough physically and mentally to survive the horror of potential combat with Iraqs veteran Army.
As it turned out, Iraq was totally routed at a cost of 137 U.S. dead for the entire war.
