In remarks to reporters, Gen. Mark Welsh, the Air Force chief of staff, says the change is unrelated to the job performance of Maj. Gen. Michael Carey, a 35-year veteran who was relieved of command last month for unspecified personal misbehavior that other officials said was related to alcohol use.
Welsh says the hiring process for nuclear commanders will now include more intensive pre-screening, to include a review of potential personal health problems.
He says Carey told him that he had engaged in "an embarrassing period of behavior." Welsh did not elaborate.
