Continuity mistake: In War Dance (4-2) the verger Mr. Yateman's wife's Christian name is Anthea. In Everybody's Trucking (8-1) it is Beryl, and in Knights of Madness (10-3) she is called Tracy.
Continuity mistake: (Colour episodes only) In the section of the closing credits that features the main cast members marching, the sky colour and positions of the shadows on the ground change depending on the actor being featured at the time (the sky is blue when Arthur Lowe, John Laurie and Ian Lavender are seen, but it is grey when John Le Mesurier, Clive Dunn, James Beck and Arnold Ridley feature). This is more obvious on episodes that have had colour restoration undertaken.
Continuity mistake: The platoon's rifles have no fore sight at various times in this episode, at other times they are fitted. Most noticeable on the railway platform and the march to camp (missing), but when they arrive at the camp, all the fore sights are on. They are missing during the outdoor training scenes - and they are missing from the credits at the end of every episode when the platoon members are shown in close up (these shots were from this episode). (00:09:00)
Continuity mistake: The Verger Mr Yeatman's first name is Maurice, but in this episode it is Henry.
Battle of the Giants! - S4-E14

Battle of the Giants! - S4-E14
Continuity mistake: When Mainwaring and Square, driving the vans, are trying to push each others' van off the bridge, Hodges parks his motorbike at the end of the bridge behind the eastgate platoon's van. In all the following shots Hodges' motor bike has disappeared.
Continuity mistake: When the second bottle thrown by Pike lands on the floor, the glass from the first bottle has all disappeared.
Continuity mistake: At the end when they line up for The Royal Train to pass there are six platoon members amongst those present, Private Frazer is not one of them. However, after the train passes and they are shown wet in head shots, he is present. As the camera pans out, we are back to the original six.
The Making of Private Pike - S9-E2
Continuity mistake: In this episode, Captain Mainwaring was given a new staff car. However, he already has one from S7 E5, The Captain's Car. What happened to the previous one is never explained, and surely he would not lose all reluctance to accept the job if he already had a staff car?
Continuity mistake: In this episode Mrs. Fox's first name is Mildred, but in "Mum's Army" (5-9) her first name is Marcia.
Answer: The show is a comedy, this was played for comedic effect and to show that in times of extreme fear, in this case about to be crushed by a steam train, the men had an adrenaline surge strong enough to pedal fast enough.
