Belgian Forces fighting alongside the Allies during World War Two included two airborne units, the Belgian Independent Parachute Company, and a Belgian Special Air Service (SAS) Squadron. Both units wore British-made Denison parachutist smocks in a unique, hand-painted "brushstroke" camouflage pattern that later spawned a large branch of derivative patterns that are still used today. Following the war, the Belgians reproduced several variations of the brushstroke pattern, which continued in use primarily with Airborne and Commando units well into the 1970s. Alongside the brushstroke pattern, Belgium also introduced its own indigenous camouflage pattern, nicknamed "jigsaw" for its resemblance to multicolored pieces of a puzzle. This pattern has continued in usage with Belgian military forces (in various incarnations) into the present era, and variations have also been produced for her former colonial possessions in Africa.
