An invasion of South Korea by the North prompted the West to action on June 25th, 1950. The war would grow to become a long and bloody one and rely on both manpower and machine to win back the initiative. One of the primary components of the assault was airpower and, within this, the first jet-versus-jet duels took place. Prop-driven aircraft were still used in number with many holdovers from the World War 2 period but the jet age was here to stay and embodied in the Soviet Mikoyan-Gurevich MiG-15 and the North American F-86 Sabre types. The conflict would end in an uneasy armistice which remains to this day - keeping the Peninsula as volatile as ever.
