Fair Winds and Following Seas - S10-E22
Continuity mistake: The opening scene, which is a replay of the ending scene from the previous episode, is slightly different. When Gen. Cresswell tells Mac she'll be stationed in San Diego, Harm comments "It's only a five hour plane ride" instead of "it's only five hours away", and when Rabb is promoted to Captain, Cresswell briefly pauses at "it's" when he says "By the way, it's a captain's billet", while there was previously no pause.
Continuity mistake: The aircraft carrier used in this episode, the USS Coral Sea, had the correct hull number on the ballcaps worn by the crew - CV-43, but the hull number displayed on the ship was "65". CVN-65 is in reality, the USS Enterprise.
Continuity mistake: In season 1, episode 10, Harm is a Lt. Commander. In episode 11, he is back to Lieutenant.
Visible crew/equipment: When Harm and Webb walk into Harm's apartment talking about Harm's brother, a crew member can be seen.
Visible crew/equipment: When Rabb and Bud meet Elaine on the beach a boom Mic is visible.
Continuity mistake: Just before Kate asks Rabb if he was a pilot she starts to take a drink from her cup. The shot changes she starts to take a drink again. (00:38:30)
Adrift (1) - S6-E24
Character mistake: When asking Skates if she saw Rabb eject, she is referred to as Commander when her rank is Lieutenant. (00:40:10)
Factual error: In the opening scene the caption states "Antwerp, Belgium Diamond District", however, the street show is actually located in Amsterdam, The Netherlands. The building at the end of the street is the "Rijksmuseum" (famous for Rembrandt's "Nachtwacht"). Furthermore, the 2 diamond experts speak German. If it was in Antwerp, they should have been speaking Dutch or Flemish.
Continuity mistake: When Captain Boone descends to engage the Hind, they are in forested mountains. It then cuts to the Hind, and there are no trees, then after the tomcat crew punch out, the RIO is hanging in the trees. The scenes that showed the Hind were cut from the movie Red Dawn.
Continuity mistake: When Lt. Roberts is held hostage in Admiral Chegwidden's office with the Admiral and the Major, he mentions a sister named Winifred. She is never mentioned again throughout the series. In later seasons it is implied that Lt. Roberts only has one sibling, a brother named Mikey.
Continuity mistake: When Ducky is performing the autopsy on Lt. Singer, Vivian dabs a vapor neutralizer under her nose, screws the top back on, and puts it in her pocket. In the following wide shot, she screws the lid on again and puts it in her pocket a second time. (00:15:35)
Continuity mistake: When Mac talks to Webb at the end of the episode, she remains still on the couch, but then her hands suddenly appear up in front of her face. (00:41:35)
Continuity mistake: After Big Bud punches Dobie, younger Bud is visible having run around a corner to help break up the fight. In the next shot, Bud is nowhere to be seen and he runs around the corner again. (00:12:30)
Continuity mistake: When the armored car with the money arrives, the scene starts with the time 10:32 typed on the screen. It is full daylight and shadows are short, so this is consistent with the printed time. When the next armored car arrives empty, it is supposed to be one hour later, but it is pitch dark. The characters say that the first truck came at 17:00 hours (which would be 5:00 p.m.) and the truck before them was scheduled for 18:00 hours.
Other mistake: After the first meeting with the JAG team and Secretary Blair to negotiate The Return of the F-14, Captain Fuente refers to Meg as "lieutenant commander". Harm is the LCDR; Meg is a lieutenant, junior grade. It's not just a character mistake: Meg's shoulder insignias indicate her rank. (00:24:30)
High Ground - S1-E16
Audio problem: When Meg is preparing to join the Marines to search for Harm and Gunny Crockett, Col. Gordon warns her to cover her back. His mouth is very obviously saying "cover [your] ass."
Fair Winds and Following Seas - S10-E22
Character mistake: Characters occasionally refer to Rabb as "Commander", even though they know he was promoted to Captain.
Continuity mistake: When Admiral Chegwidden hands Petty Officer Coates a dress of hers he found in the galley, Coates' grip on the hanger changes between shots. (00:09:35)
Answer: Officially, the individual has been ordered to attend, failing to could be interpreted as either, Failure to follow orders, dereliction of duty, going AWOL, or even desertion. It would depend on the underlying reason as to why the person doesn't appear.
