District Voluntary Force

District Voluntary Force (DVF) is a special constabulary unit of the Odisha Police. They are primarily used in anti-Maoist operations. It was formed in 2009.
Organisation.
Odisha has 500 personnel under the DVF. They do not wear special lapels or badges. 40% are recruited from former Special Operation Group (SOG) agents, as they retire after 35; and rest from the local police who speak the local dialects and know the terrain. They work in groups of 8–10. Some of them gather information and other carry out operations. They don't require the approval of Superintendent of Police for operations, unlike the SOG. However for bigger operations, SOG is sent to avoid casualties, as DVF lacks the training. DVF agents have 30% higher salary than the local police.
In January 2011, the state government announced that they would increase the number of DVF personnel. The number of district with DVF units would be increased from 11 to 17.
