Jocke Unger played drums in Swedish melodic metallers Supreme Majesty. The band and Unger parted ways in August 2004. A posting on the group's web site stated:

"Jocke has other engagements he wants to focus on, among these full-time drumming in the thrash metal band Sgt. Carnage. Replacing Jocke behind the drum set is the well experienced and talented drummer Johan Rydberg (ex-Sanzia, In Black)."
