The Wyoming Cavalry are an American professional indoor football team based in Gillette, Wyoming. The Cavalry began play in 2000 as an expansion member of the original Indoor Football League as the Casper Cavalry. The Cavalry became a charter member of the National Indoor Football League (NIFL) in 2001 following the original IFL's purchase by the Arena Football League's Orlando Predators. They were most recently members of the Intense Conference in the Indoor Football League (IFL). The move in 2001 also brought a franchise name change to the current Wyoming Cavalry. The team then joined the American Indoor Football Association (AIFA) in 2008 after the NIFL's demise. With the AIFA's presence in the Western United States dwindling, the Cavalry joined the IFL in 2011. In September, 2014, majority owner Mitch Zimmerman announced that the team would cease operations.
