Factual error: A number of the soldiers on the US Army base have haircuts/hairstyles completely against army rules and regulations. This is particularly noticeable given the show is set in the late 90s, when the US Army was much stricter about haircut rules for serving military members. In real life, they wouldn't be allowed to have those hairstyles.
