Sharon was a commander in the Israeli Army from its creation in 1948. As a soldier and then an officer, he participated prominently in the 1948 Palestine war, becoming a platoon commander in the Alexandroni Brigade and taking part in many battles, including Operation Bin Nun Alef. He was an instrumental figure in the creation of Unit 101 and the reprisal operations, as well as in the 1956 Suez Crisis, the Six-Day War of 1967, the War of Attrition, and the Yom-Kippur War of 1973. Yitzhak Rabin has called Sharon "the greatest field commander in our history".
