With the exception of the Kasernierte Volkspolizei, whose grey-green uniforms follow the style of the East German National People’s Army (Nationale Volksarmee - NVA), all Volkspolizei services wore the same basic uniform adopted in 1956 when it was officially established. There were various kinds of uniforms, worn according to the work or social situation and differing in material for summer or winter wear. Most uniforms — service, semi-dress, and parade — are gray-green but the transport police wore dark blue.
