The Hitmen began as the Chicago Force of the Central States Hockey League. That team will continue to operate alongside the NAHL's Hitmen, and will also take on the Hitmen name for 2010-11. In November 2010 the CSHL fell under the direction of the NAHL and changed its name to the North American 3 Hockey League (NA3HL).
The Hitmen will also field a team in the Great Lakes Junior Hockey League (GLJHL). The team previously played at the Tier III Jr. C level as the Chicago Huskies and plays at the International Ice Center in Romeoville, Illinois. The league advanced to the Tier III Jr. B level beginning in the 2010-11 season.
