He worked for Nimrod Strange, commander of the Third World Slayers. The Third World Slayers were a army made up of extreme leftist and rightist terrorists. Master Sniper was sent to kill Benjamin Abramon, one of Marc Spector's (Moon Knight) long time friends in the espionage business. He found his target visiting Spector at his mansion in New York and took him out, but not before Abramon divulged enough intel to Marc Spector about Nimrod Strange, the Third World Slayers and Master Sniper. Thanks to a piece of microdot found on Abramon's body, Moon Knight was able to track Master Sniper to Switzerland where he confronted the assassin. Master Sniper was buried by an avalanche after a brief brawl with Moon Knight.
