Character mistake: When the Marines are navigating through the Paris Island obstacle course, Hartman is shouting "It should take you no less than 10 seconds to negotiate this obstacle!" In other words, the LONGER it takes someone to get across, the better? (00:13:27)
Character mistake: When Cronauer and Garlick get stuck in traffic with the Army trucks, Garlick asks the assembled troops to guess who is in the Jeep with him. One of the troops shouts "Mork". Robin Williams played Mork in Mork & Mindy, but not until 1978, well after the setting of this film.
Character mistake: On the handwritten label Bond finds, Bratislava is written Bratislavia.
Character mistake: After Ricky has just killed his girlfriend with the car antenna, he's challenged by a police officer. Officers would never walk right up to someone who have just committed a murder. Police would always order the suspect into a position that presents the least amount of threat and minimal chance of resistance. Grabbing the officer's gun would never had been an option.
Character mistake: In the final scene of the film where Axel is leaving, and Taggart says "See you around." when Axel turns around to start driving he says "Be cool Rein..." He accidentally uses the surname of the actor, Judge Reinhold, who plays Billy Rosewood. However he cleverly tries to cover it up by trailing off his sentence as he knows he has made the mistake. (01:34:15)
Character mistake: During the movie, Stallone Lincoln Hawk is referred several times as 'Hawks' by other characters (the police officer retrieving him from his cell, as well as his former father-in-law, who should know his real name). Lincoln actually calls himself Hawkes before he crashes the gate.
Character mistake: When Modoc is suggesting what type of blood to drink, he suggests pigs blood B-. Swine don't have B blood. They have A and O blood only.
Character mistake: When Mac describes what he saw after Blaine was killed, he states that he "capped off 200 rounds with the minigun." At the rate the minigun fires, and the length of time Mac was shooting, he fired at least 10 times that amount. Perhaps he meant to say "capped off 2000 rounds." This adds to another mistake: the ammo pack Blaine carried only holds 500 rounds but much more than that is fired during the course of the film.
