Continuity mistake: When the Walmington platoon stop their van to open the gate to let the sheep out in attempt to hold up the Eastgate platoons van the Eastgate van drives through the gate into the field with Hodges on his motorbike following, but when the camera cuts back to the road the Eastgate van and the motorbike are on the road behind Walmington's van, the Eastgate van and the motorbike are next seen coming out of the field further up the road.
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.
Continuity mistake: When Mainwaring asks the engineer if he is through to the producer in London yet the squad are lined up from left to right - Fraser, Pike, Wilson, Mainwaring, Jones, Walker and Godfrey. Then the angle changes and the order is now Fraser, Jones, Pike, Mainwaring and Walker. Then another angle change and it's back to the first line up.
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).
