styled cap is modeled after the Japanese custom in the Maritime Self-Defense Force, in turn the design used by many European navies. For ceremonial parades, a variant known as Pakaian Dinas Parade (PDP, Parade Full Dress) is worn by parade commanders. However PDP can also be a variant of the combat dress uniform pattern. The parade commander wears a M1 or PASGT helmet instead of the normal peaked cap. Israel Each arm of the Israeli Defence Force (IDF) ground forces, Navy and Air Force has its own dress uniform, with separate versions for summer and winter. These are similar in style to civilian business dress suits, or to the service dress uniforms worn by the British forces. The dress uniform includes a blazer-type jacket, worn with a white shirt, and a tie. The ground forces uniform is dark green, with a single-breasted, three-buttoned jacket and tie of the same colour. Headgear worn is the beret. The air force uniform is of the same design, but medium blue. The naval uniform has a darker blue, double-breasted, six-buttoned jacket, with gold-coloured rank insignia on the cuffs, worn with the peaked cap.
