A slick (Hebrew: סליק, noun form of the Hebrew root ס-ל-ק, "to remove"[1]) is a type of hiding place for weapons. They were used by the militant Zionist groups operating in Mandatory Palestine, including Haganah, Lehi and Irgun.[1] They were built all over the country in order to provide easy access to weapons, which were used to protect settlements and carry out offensive operations.
