The Volkswagen Kübelwagen (   ) (literally, "Tub" car, previously mostly used for rail, industrial or agricultural hopper cars) was a light military vehicle designed by Ferdinand Porsche and built by Volkswagen during World War II for use by the German military (both "Wehrmacht" and "Waffen-SS").
 Based heavily on the Volkswagen Beetle, it was prototyped as the Type 62, but eventually became known internally as the Type 82.
The "Schwerer Wehrmachtschlepper" (Heavy Military Tractor), or sWS, was a German World War II half-track vehicle used in various roles between 1943 and 1945.
 The unarmored models were used as supply vehicles and as tractors to haul artillery.
 Armored versions mounted anti-aircraft guns or a 10 barrel rocket launcher ("Nebelwerfer").
 Less than a thousand were built before the end of the war, but production continued after the war of an improved model in the Tatra plant in Czechoslovakia.
The Scammell Scarab is a British 3-wheeled tractor unit produced by the truck manufacturer Scammell between 1948 and 1967.
 Its name is commonly believed to be derived from the rounded bonnet that resembled the elytra (wing covers) of a Scarab beetle, but the name really comes from a more conventional source, Scammell's idea of the combination of an Arab horse (which the Mechanical Horse replaced in BR usage) and the word Scammell.
 Sca-rab = Scarab.
 The official Scammell Lorries Ltd advertisement film makes reference to this.
 It was extremely popular with British Railways and other companies which made deliveries within built-up areas.
 The Ministry of Defence also used the Scarab and trailers for predominantly internal transport on large military bases.
