Around the world the Salvation Army have Emergency Services Support Units throughout the country. These are mobile canteen vehicles providing food and other welfare to members of the Emergency Services such as bushfires, floods, land search, and other both large- and small-scale emergency operations undertaken by Police, Fire, Ambulance and State Emergency Service members, and the general public affected by these events. Volunteers and officers run the canteen service and the response policy is to respond when emergency services have been on the scene for more than four hours or where four or more Fire vehicles are responding.
