Obsolete badges of the United States military are a number of U.S. military decorations which were issued in the early 20th century leading up to and including badges issued during the Second World War. Such badges were eventually phased out of the United States armed forces in favor of the modern military badges which are used by the U.S. military today. Certain badges were also issued in the 19th century and the oldest military badge on record dates to the time of the American Revolutionary War. The following is a listing of obsolete U.S. military badges and the time period, or branch of service, to which such badges were specific. "Hap" Arnold wearing (above ribbons) conventional "wings" design and (below ribbons) Military Aviator Badge A unique obsolete badge situation occurred with General of the Air Force Henry H. Arnold who received the first style of military aviator badge, an eagle hanging down from a bar. Quickly replaced by the more conventional "wings" design, he simultaneously wore both types throughout his career.
