 The markings consisted of one long white strip in the middle of the vehicle from the front and across the roof all the way to the back with two additional strips in the middle of both sides.This is similar to the markings applied on most Soviet tanks and armoured fighting vehicles fighting in Berlin in 1945 during the Second World War to prevent friendly fire from Western Allied (British or American) aircraft that flew over the city to conduct bombing raids until its fall.In addition to that, certain Soviet Air Force's aircraft, such as the MiG-21 fighters, were given two red stripes on their fuselages and vertical stabilisers, also because these types of aircraft were used by the Czechoslovak Air Force.
