Initially thousands of Iraqi infantrymen engaged the U.S. 3rd Armored Division with Sagger antitank missiles and RPGs from dug in defensive fighting positions. The Iraqi defensive network also consisted of bunkers and dug in vehicles. The Iraqis also had the support of a dozen field artillery batteries directly behind the rear of the Tawakalna Republican Guard Division. There were no soft or exposed Iraqi flanks to exploit. The 3rd Armored Division overcame these Iraqi defensive positions utilizing superior command and control along with well coordinated combined arms tactics.
