For many years the Southern Command was tasked with defending the Negev and securing the border on the Sinai Peninsula from Egypt. The Southern Command led IDF troops in five wars against Egypt: the 1948 Arab–Israeli War, the Suez War, the Six-Day War, the War of Attrition, and the Yom Kippur War. This high operational activity and its demanding toll resulted in the Southern Command's Alufs (SCA) being replaced fairly rapidly.[2]
The most famous leadership replacements took place in 1973, during the Yom Kippur War when Shmuel Gonen was suspended as the SCA due to repeated disputes with Ariel Sharon, who was the previous SCA. The government-appointed Haim Bar-Lev, who was the former Chief of the General Staff, as the new SCA in an emergency directive. After the Egypt–Israel peace treaty, the southern front remained quiet and most of the activity centred on guarding the borders from smugglers and fluid security over the Gaza Strip.
From 2004, the fighting in Gaza became especially intensive, and on the IDF's part, included targeted killings, short armored expeditions, and efforts to locate and destroy the smuggling tunnels used by Palestinian militant groups to obtain weapons.
During 2005, the Southern Command was involved in the unilateral Gaza disengagement plan, initiated by Ariel Sharon (Prime Minister of Israel, 2001–2006), which mainly entailed the removals of all Israeli settlements from the Gaza Strip and back to the Israeli side of the Green Line. The Command re-situated itself north of the Gaza fence. The Philadelphi Route was given to Egypt, who did not prevent the movement of thousands of Palestinians between the Gaza Strip and the Sinai through the city of Rafah. As of 2006[update], the attempt to infiltrate Israel to perform suicide bombings and the launch of Qassam rockets, especially by Islamic Jihad and the Popular Resistance Committees, remains ongoing and is the central focus of the Southern Command.
