Union continued the massive build-up of the Indian military and a US arms embargo forced Pakistan to look at other options. It turned to China, North Korea, Germany, Italy and France for military aid. China in particular gave Pakistan over 900 tanks, Mig-19 fighters and enough equipment for three infantry divisions. France supplied some Mirage aircraft, submarines. The Soviet Union gave Pakistan around 100 T-55 tanks and Mi-8 helicopters but that aid was abruptly stopped under intense Indian pressure. Pakistan in this period was partially able to enhance its military capability. Involvement in Arab conflicts Pakistan had sent numerous military advisers to Jordan and Syria to help in their training and military preparations for any potential war with Israel. When the Six-Day War started, Pakistan assisted by sending a contingent of its pilots and airmen to Egypt, Jordan and Syria. PAF pilots downed about 10 Israeli planes including Mirages, Mysteres and Vautours without losing a single plane of their own. Jordan and Iraq decorated East Pakistani Flight Lieutenant Saif-ul-Azam. Israelis also praised the performance of PAF pilots. Eizer Weizman, then Chief Of Israeli Air Force wrote in his autobiography about Air Marshal Noor Khan (Commander PAF at that time): "...He is a formidable person and I am glad that he is Pakistani and not Egyptian." No Pakistani ground forces participated in the war. After the end of the Six-Day War, Pakistani advisors remained to train the Jordanian forces. In 1970, King Hussein of Jordan decided to remove the PLO from Jordan by force after a series of terrorist acts attributed to the PLO, which undermined Jordanian sovereignty. On September 16, King Hussein declared martial law. The next day, Jordanian tanks attacked the headquarters of Palestinian organisations in Amman. The head of Pakistan's training mission to Jordan, Brigadier-General Zia-ul-Haq (later President of Pakistan), took command of the Jordanian Army's 2nd division and helped Jordan during this crisis. Pakistan again assisted during the Yom Kippur War, sixteen PAF pilots volunteered for service in the Air Forces of Egypt and Syria. The PAF contingent deployed to Inchas Air Base (Egypt) led by Wing Commander Masood Hatif and five other pilots plus two air defence controllers. During this war, the Syrian government decorated Flight Lieutenant Sattar Alvi when he shot down an Israeli Mirage over the Golan Heights. The PAF pilots then became instructors in the Syrian Air Force at Dumayr Air Base and
