WASHINGTON (AP) — The Air Force general who was fired from command of U.S. land-based nuclear missile forces had engaged in “inappropriate behavior” while on official business in Russia last summer, including heavy drinking, rudeness to his hosts and associating with “suspect” women, according to an investigation report released Thursday.

The events that led to the dismissal took place while Maj. Gen. Michael Carey was in Russia in July as head of a U.S. government delegation to a nuclear security training exercise. At the time, he was commander of the 20th Air Force, responsible for all 450 of the Air Force’s Minuteman 3 intercontinental ballistic missiles stationed in five U.S. states.
