A newly declassified document has revealed the general in charge of the US Air Force's long-range nuclear missiles was sacked for conduct "unbecoming of a gentleman" during a trip to Russia in July.
The document says Major General Michael Carey drank too much and met "suspect" foreign women and danced with them.
The BBC reprots he was responsible for 450 maintaining intercontinental ballistic missiles at three bases.
No details were given when he was removed in October. He is now special assistant to the commander of Air Force Space Command.
In September, the US Navy sacked an admiral overseeing nuclear forces over gambling at a casino. Vice-Admiral Tim Giardina was deputy head of US Strategic Command.
