Bruce debuted in World Championship Wrestling in 1989, using his real name as a preliminary wrestler, then earned some undercard notoriety as Sgt.

[4] He later became a member of the Dungeon of Doom, under the short-lived identity of Braun The Leprechaun[1] before again being repackaged as "Military Man" Jack Boot.

Bruce was also notable for being the first wrestler to lose to newcomers (to WCW) such as "Cowboy" Bob Orton, Jr (who had an almost unbeaten streak in the company around the time) and The Iron Sheik.

While Bruce has been criticized for his intense workout sessions while in charge of the WCW Power Plant, he is also remembered in a positive light, especially when recounting many of the notable performers he trained during his tenure in WCW, such as Bill Goldberg, Big Show, Chuck Palumbo, Mark Jindrak, Sean O'Haire, Mike Sanders, Stacy Keibler, Daffney and Torrie Wilson.

Batista claims that, when he went for an open tryout at the WCW Power Plant, Bruce drilled him into the ground with an intensely-grueling workout regimen, causing him to throw up viciously.

In addition to his authority role, he is known to agent & critique matches on the events as well as holding training with many of the independent performers on those cards.
