Like every other town, Walmington-on-Sea is to have its War Weapons Week. The event is to be marked by a parade of all Auxiliary Services such as the Wardens, Auxiliary Fire Service, the nurses, the Rescue Squad and of course the Home Guard. The whole procession is to be led by the drum and bugle band of the Sea Scouts. Captain Mainwaring decides that the platoon should be led by a mascot.
