The Iserlohn Roosters are a professional ice hockey team based in Iserlohn, North Rhine-Westphalia. They are members of the Deutsche Eishockey Liga (DEL) since 2000 and play their home games at the Balver-Zinn Arena which is also known as Eissporthalle am Seilersee. The team made the playoffs three times in its first 15 seasons in the DEL. The Roosters are widely regarded for their fans and having one of the best atmospheres at home games in Europe despite having an arena capacity for just 4,967 spectators. The club caused much controversy in 1987 when, under Heinz Weifenbach, a US$900,000 advertising deal was signed for former Libyan leader Muammar Gaddafi's The Green Book. The book is widely acknowledged as having been inspired by Mao Zedong's The Little Red Book.
