Factual error: When Riggs and Murtaugh go to investigate the scene where the body of Ramon Alvarez is discovered Scorsese states that Alvarez's dog tags say "SEAL" on them. His dog tags would not say that he is a SEAL on them. The information listed on dog tags is as follows: Name, Social Security Number, Blood Type, Service Branch, and Religious Preference. There is no way to tell what a given service member's MOS (job) from his or her dog tags. (00:14:00)

Factual error: In Chad Jackson's resume, it says he was assigned to "SEAL Team Delta." Navy SEAL teams are ranked by number (ex. SEAL Team 3, 10, etc.), there is no such unit called SEAL Team Delta.
