with the reinforcement of the far east air forces (feaf), air national guard squadrons were deployed to europe in late 1950, being assigned to newly constructed bases in france as part of united states air forces in europe (usafe). these deployments helped reinforce the nato commitment of the united states in case the combat in korea became part of a wider conflict with the soviet union. beginning in february 1951, mobilized units were assigned to air defense command (adc), strategic air command (sac) and tactical air command (tac), replacing or augmenting active duty units. air national guardsmen assigned to adc also were assigned to various aircraft control and warning as well as radar calibration units. their organizations either strengthened american air defenses or were converted to tactical air control units that directed air force fighter aircraft in the continental united states, alaska, newfoundland, europe, and french morocco.
