Oak leaf cluster
[3] The following are examples of the first through twenty-first awards of an Army Commendation Medal with the bronze and silver oak leaf clusters: Oak leaf clusters may be worn on Department of Defense, Department of the Army, and Department of the Air Force decorations and awards presented to members of the eight uniformed services: the Army, Navy, Marine Corps, Air Force, Space Force, Coast Guard, Public Health Service, and the NOAA Commissioned Corps.Except for the Air Medal, unique decorations and awards issued by Department of the Army or Department of the Air Force, and those decorations and awards issued by the Department of Defense, the other uniformed services use 5⁄16 inch stars to indicate subsequent personal decorations only; a gold 5⁄16 inch star is equivalent to a bronze oak leaf cluster, while a silver 5⁄16 inch star is equivalent to a silver oak leaf cluster.After World War II, Iron Crosses awarded previously could be worn by the recipient provided the swastika was replaced by oak leaves.In earlier times, the Pour le Mérite, the highest military order in the Kingdom of Prussia, could also be awarded with oak leaves.A civil version of the order, for accomplishments in the arts and sciences, still exists in the Federal Republic of Germany.
