 A citizens' militia modeled on the British Home Guard called the Volunteer Defence Corps (VDC) was founded by the Returned and Services League of Australia (RSL) in 1940 in response to the possibility of a Japanese invasion of Australia.In the beginning, members didn't have uniforms and often paraded in business attire.They were given instruction on guerrilla warfare, and later the private organization was taken over by the Australian Government and became part of the Australian Military Forces (AMF).
