Battledress (BD), or later No. 5 Uniform, was the combat uniform worn by British Commonwealth and Imperial forces and many Free European Forces through the Second World War. It was worn mostly but not exclusively in temperate climates. In some armies it continued in use into the 1970s. During the Second World War and thereafter this uniform was also used for formal parades (including mounting the Guard at Buckingham Palace) until the re-introduction of separate parade uniforms in the late 1950s.
