Dad's Army (1968)

Season 3: Episode 4

Mainwaring is extremely annoyed that the platoon – sans Godfrey, who was too slow – have used up all their ammunition firing in vain at a low-flying German aeroplane. An inquiry is ordered – along with a new case of ammunition, which duly arrives. The captain in charge, taking place in the church hall in competition with choir practice, feels it a waste of time but talks the men through what happened.
