How does the IDF work.
All branches of the IDF answer to a single General Staff. The Chief of the General Staff is the only serving officer having the rank of Lieutenant General (Rav Aluf). He reports directly to the Defense Minister and indirectly to the Prime Minister of Israel and the cabinet. Chiefs of Staff are formally appointed by the cabinet, based on the Defense Minister's recommendation, for three years, but the government can vote to extend their service to four (and in rare occasions even five) years. The current chief of staff is Benny Gantz. He replaced Gabi Ashkenazi in 2011.
