Unit_101 Unit 101 was a special forces unit of the Israeli Defence Force (IDF), founded and commanded by Ariel Sharon on orders from Prime Minister David Ben-Gurion in August 1953. It was created in order to better deal with a spate of Arab fedayeen attacks against Israelis, which the IDF was unsuccessful in halting. Unit 101 was merged into the paratrooper brigade in 1954, and later disbanded.
