war, Israel believed it could win a war in 3–4 days. The United States estimated Israel would need 7–10 days to win, with British estimates supporting the U.S. view. Armies and weapons Armies The Israeli army had a total strength, including reservists, of 264,000, though this number could not be sustained during a long conflict, as the reservists were vital to civilian life. Against Jordan's forces on the West Bank, Israel deployed about 40,000 troops and 200 tanks (eight brigades). Israeli Central Command forces consisted of five brigades. The first two were permanently stationed near Jerusalem and were the Jerusalem Brigade and the mechanized Harel Brigade. Mordechai Gur's 55th Paratroopers Brigade was summoned from the Sinai front. The 10th Armored Brigade was stationed north of the West Bank. The Israeli Northern Command comprised a division of three brigades led by Major General Elad Peled which was stationed in the Jezreel Valley to the north of the West Bank. On the eve of the war, Egypt massed approximately 100,000 of its 160,000 troops in the Sinai, including all seven of its divisions (four infantry, two armoured and one mechanized), four independent infantry brigades and four independent armoured brigades. Over a third of these soldiers were veterans of Egypt's continuing intervention into the North Yemen Civil War and another third were reservists. These forces had 950 tanks, 1,100 APCs, and more than 1,000 artillery pieces. Syria's army had a total strength of 75,000 and was deployed along the border with Israel. Professor David W. Lesch wrote that "One would be hard-pressed to find a military less prepared for war with a clearly superior foe" since Syria's army had been decimated in the months and years prior through coups and attempted coups that had resulted in a series of purges, fracturings and uprisings within the armed forces. The Jordanian Armed Forces included 11 brigades, totalling 55,000 troops. Nine brigades (45,000 troops, 270 tanks, 200 artillery pieces) were deployed in the West Bank, including the elite armoured 40th, and two in the Jordan Valley. They possessed sizable numbers of M113 APCs and were equipped with some 300 modern Western tanks, 250 of which were U.S. M48 Pattons. They also had 12 battalions of artillery, six batteries of 81 mm and 120 mm mortars, a paratrooper battalion trained in the new U.S.-built school and a new battalion of mechanized infantry.
