Heyl Clali Beret - General Service. GENERAL SERVICE OLIVE DRAB BERET. ORIGINAL GENERAL SERVICE BERET INSIGNIA. Price includes beret insignia. The IDF was founded May 26, 1948 after the establishment of the state of Israel "to protect the inhabitants of Israel and to combat all forms of terrorism which threaten the daily life". The IDF succeeded the Haganah (in particular, its operational branch, the Palmach) as the permanent army of the Jewish state. It was also joined by former elements of the Jewish Brigade that fought under the British flag during World War II. After the establishment of the IDF the two Jewish underground organizations the Etzel and Lehi joined with the IDF in a loose confederation but were allowed to operate independently in some sectors until the end of the 1948 Arab-Israeli War, after which these two organizations were disbanded, and their members integrated into the IDF.
