When a screaming Radin destroys the wall monitor after it depicts a nuclear explosion & he dives to the basement floor (from the monitor's point of view) behind the coffee table, it is completely clean; but in the instant closeup of him looking up at it, there are some plastic fragments scattered on the tabletop, but none on the floor.
Paul Radin reminds Colonel Hawthorne that, as a second lieutenant, he was subject to a court martial and received a dishonorable discharge. Officers can be discharged after a court martial, but it is not called a dishonorable discharge - it's called a "dismissal notice".
