This model is in 1/700 scale. Each aircraft is not armed, but has two external fuel tanks (One under each wing). The 12x MIG-15 aircraft are connected as a single sprue by a wire under the main body of the aircraft. Once the wires are cut the model does not require finishing.
According to Wikipedia: "The Mikoyan-Gurevich MiG-15 (NATO reporting name: "Fagot") is a jet fighter aircraft developed by Mikoyan-Gurevich OKB for the Soviet Union. The MiG-15 was one of the first successful swept-wing jet fighters, and achieved fame in the skies over Korea, where early in the war, it outclassed all straight-winged enemy fighters in most applications."
