Israel Brigadier Tat Aluf (Cloth). The Israel Defense Forces (IDF) have a unique rank structure. Because the IDF is an integrated force, ranks are the same in all services (there is no differentiation between army, navy, air force, etc.) The ranks are derived from those of the paramilitary Haganah developed in the Mandate period to protect the Yishuv. This origin is reflected in the slightly-compacted rank structure; for instance, the Chief of Staff (Ramatkal) is seemingly only equivalent to a Lieutenant General in other militaries. The Order is for Pair Ranks.
