What does "firing" mean when the US military "fires" a commander? Is it different than being "relieved of duty"?
(E.g., it was reported today in the NY Post that in the aftermath of the incident where US sailers got captured by Iran near Farsi island on January 12 2016 that "In addition to Moses, the Navy last month fired Eric Rasch, commander of the squadron that included the sailors." And I've seen it in other articles too, recently, e.g., about a death by "hazing" during training in the USMC where "So far, at least two leaders at Parris Island have been fired in connection with an investigation into Siddiqi’s death". The latter quote was from the Marine Corps Times where the reporter may be presumed to know the proper terminology, so I'm guessing it isn't just a newspaper shortcut.)
