By 20 March, Jordan had identified parts of the Israeli 7th Armored Brigade, 60th Armored Brigade, 35th Paratroop Brigade, 80th Infantry Brigade, a combat engineer battalion and five artillery battalions between Allenby and Damia bridges. The Jordanians assumed the Israelis were planning an attack with a drive on Amman, and the army took up positions near the bridges, with the 60th Armored Brigade joining the 1st Infantry Division. Jordan also added most of its armored car, antitank and artillery units to the 1st Infantry Division. The total firepower was 105 Patton tanks and 88 artillery pieces. The infantry divisions were deployed near the bridges, each with a tank company. The artillery was mostly deployed on the higher Jordan Valley ridges overlooking Karameh for topological advantage.
