Nuclear Assault is a Thrash metal band formed in 1985. As a bass player, Dan Lilker left Anthrax after performing on their album Fistful of Metal. He left Anthrax in search of more aggressive music to play and founded Nuclear Assault with vocalist and guitarist John Connelly, who was also a member of Anthrax for a short time. Guitarist Mike Bogush and drummer Scott Duboys lasted only briefly before being replaced by guitarist Anthony Bramante and drummer Glenn Evans.
