The franchise began as an expansion team to the NAHL in 2005. The team played in the town of Owatonna, Minnesota as the Southern Minnesota Express. After the 2007–08 season, it was announced that the Express would relocate to the Detroit Area, where they would be called the Motor City Machine. The Owatonna, Minnesota market was granted a new franchise with a similar name, the Owatonna Express.
On June 26, 2009, the team announced it was changing its nickname to the Metal Jackets, and removing the triangle and text from the logo. 
On May 7, 2011, it was announced the team was moving to Jamestown, New York to become the Jamestown Ironmen, named after record setting Jamestown Jet Alumnist, Johnathan "The Ironman" Andhor. In reality, the team was named in a county wide contest and focuses on the cities history as an "iron making" community. It also had a lot to do with the upcoming Ironman movie series that was scheduled to be released. The city's current Junior A hockey team, the Jamestown Jets, unsuccessfully filed a lawsuit over the move, alleging a conspiracy to remove the Jets in favor of the Ironmen.
In February 2013, Ironmen owner Kenji Yamada indicated he may put the team up for sale due to falling attendance. Yamada stated that he does not want to move the team out of Jamestown. On May 5, it was reported that a deal was completed between a group of local investors and a separate faction to buy the team from Yamada, which would keep the team in Jamestown. This deal ultimately collapsed, and on June 5, 2013, Yamada announced the Ironmen would not return for the 2013–14 season.
