The Dayton Demolition was a minor league professional ice hockey team in the Federal Hockey League based in Dayton, Ohio and played their home games at Hara Arena. The team was known as the Berkshire Battalion in North Adams, Massachusetts before it relocated to Dayton in July 2015 to replace the defunct Dayton Demonz after failing to come to an arena agreement.

Hara Arena was a 5,500-seat multi-purpose arena located in the Trotwood, Ohio suburb of Dayton. The facility began as a ballroom in 1957, added an arena in 1964 and grew to a six-building complex which closed in August 2016.
