Factual error: At the end of the movie WOPR tries to crack the launch-code using brute force. So far so good. When WOPR finds out one digit of the 10 digit code, the first digit locks and the search goes on with the remaining 9 digits. Then he finds the second one, it locks too and so on. Problem is, brute force doesn't work that way. It would be too easy (26 letters and 10 numbers = only 36 possibilities for one digit). Brute-Force works only "all or nothing", you can't sneak your way to the whole code one by one.

Stephen Falken: The whole point was to find a way to practise nuclear war without destroying ourselves. To get the computers to learn from mistakes we couldn't afford to make. Except, I never could get Joshua to learn the most important lesson.
David Lightman: What's that?
Stephen Falken: Futility. That there's a time when you should just give up.
Jennifer: What kind of a lesson is that?
Stephen Falken: Did you ever play tic-tac-toe?
Jennifer: Yeah, of course.
Stephen Falken: But you don't anymore.
Jennifer: No.
Stephen Falken: Why?
Jennifer: Because it's a boring game. It's always a tie.
Stephen Falken: Exactly. There's no way to win. The game itself is pointless! But back at the war room, they believe you can win a nuclear war. That there can be "acceptable losses."
Trivia: A very early reference to computer "firewalls" is mentioned in this film.
Question: At the beginning of the film, who were the two men in uniform and why did one pull a gun on the other?
Answer: Actually it would take four men; two men in two separate LCCs (Launch Control Centers) to corroborate. In fact, there are five LCCs in a Squadron and the others can even "inhibit" an erroneous launch order coming from a single LCC.

Answer: They were erroneously alerted that an actual nuclear attack was underway, and they had been trained to respond by firing a nuclear warhead. However, one was unconvinced that the US was actually under attack, and he wanted further confirmation from his superiors. The other insisted that they follow protocol and fire the missiles. One man alone cannot launch the missiles, it takes two, and the one with the gun is attempting to force his partner to follow through on launching the weapon.
