Westminster ARP wardens use scale models of buildings to help with their training.
Part of issue THIS ENGLAND.
High angled shot of bomb site. Various shots of ARP (Air Raid Precautions) wardens in training. An instructor stands in front of a blackboard, the wardens sit around a scale model of Westminster with office blocks and churches. The lights in the meeting room are turned out. The original model is replaced with another, similar to the first except some of the buildings have been demolished. The wardens have to access the damage and report to chief ARP warden, as they would in a real air raid. The ARP wardens call the model the "tactical table".
