Read Ralph Peters today for a vivid description of the battle being fought south of Baghdad by the 3/7th Cav:
The forces rushing south have at least one specific mission: Destroy 3/7 Cav. The Iraqis hope that the squadron has been weakened - although the best that Iraqi attacks along the route of march achieved was to disable - not destroy - three U.S. tanks.
Nonetheless, the Cav's toughest fight is on as I write. Because of the weather, some of those Iraqi fighters likely will get through, along with some Republican Guard armor. And the weather does hurt the ability of the Cav's tanks and infantry combat vehicles to detect and engage enemy targets at long range.
This battle is a knife fight.
