The platoon is given heavy artillery and, directly in the line of fire of their naval gun, the town's bandstand is at grave risk.
Captain Mainwaring and Sergeant Wilson are discussing a church parade in the Vicar's office when they are interrupted by the Verger, accompanied by an official from Pickfords, complaining that a large artillery gun has been left in the yard.
The next day, the platoon organise a TEWT (Tactical Exercise Without Troops) and make a miniature version of Walmington to test their new battle strategy, using, among other things, a powder puff, a scrubbing brush and a bottle of whisky.
Mainwaring orders the destruction of the cricket scoreboard (much to Wilson's annoyance), the allotments (to Frazer's disapproval) and the bandstand (to the dismay of Jones, who reveals that he was present when it was erected and dedicated to Queen Victoria) within 48 hours.
Mr Rees has had enough at this point and promises to tell his committee that "they can sleep sound in their beds, provided they make them inside that enemy tank".
