'Battle of the Bulge' is an excellent case of both. That's where the diesel tank column rushes to capture a supply of gasoline.
The only good scene in that movie is when Robert Shaw is reviewing his tank commanders and they sing "Panzerleid". The Germans had good songs.
"Zero Dark Thirty", a mostly very good movie, had the CIA station chief in Pakistan wearing a CIA lapel pin! Most of the Americans know who's CIA and who's not, but you don't advertise--especially since your typical diplomatic installation has a lot of local employees.
