However, there remained too many signs for the Israelis to ignore, chief among which was the hasty Soviet evacuation from Cairo and Damascus, and the constant buildup of forces on the Syrian front when Egypt, it was assumed, would not enter war. Though the Chief of Staff, David Elazar, was assured that the probability of war remained low, he took precautionary steps on October 5. Elazar placed the entire military on alert, canceled all leaves, and ordered the Air Force to assume a full-alert posture. He also ordered the 7th Armored Brigade to relocate from the Sinai to the Golan Heights. This raised Israeli numbers in the Golan Heights to 177 tanks and 44 artillery pieces on October 6. To replace the 7th Armored Brigade, the Armor School, under the command of Colonel Gabi Amir, was ordered to activate its tank brigade for immediate airlift; it was in the Sinai by October 6, before the war began. Ultimately though, no orders for mobilization were issued to reservists; Elazar and other senior commanders still expected a 24- to 48-hour warning from the intelligence services if the Arab nations were bent on war.
