* BackedByThePentagon: At the end of the credits: "Special appreciation to the United States Marine Corps for their cooperation and valued assistance."
* TheDanza: Gerald "Mac" [=McRaney=] as Major John "Mac" [=McGillis=].
* OutOfOrder: The final two season 4 episodes aired out of sequence. From a chronology perspective the change made little sense. In the penultimate episode, [[spoiler:everybody was transferred to Washington DC with a new general taking over in Hollister]]. In the final episode that aired, [[spoiler:everybody was back in Hollister as if nothing had changed]].
