It's called "whispering death" and was responsible for more battlefield damage in a matter of moments in the first Gulf War than most infantry units did all day. The fact is that a single battalion, fully loaded with tactical ammo (as opposed to training ammo) of M1A2 Abrams tanks is more than a match for an Iraqi armored brigade. Not one M1 was KIA due to enemy action during the entire 100 hours of ground combat. NOT ONE. If there is any American armor on the ground (and I know there is--it was prepositioned just in case) they are already fully capable of self defense. Saddam is crazy but he's not suicidal.
