British Home Guard
The Home Guard existed from 1940 to 1944. It was composed of one and a half million volunteers who were otherwise not allowed to go into military service. The main reason for this was old age. This led to the nickname "Dad's Army". The Home Guard guarded the coastal areas of Britain from enemy threats, like paratroopers. They also helped guard some industrial areas, such as factories and airfields. It was widely popularised after the war by the comedy show Dad's Army.
