Baker (portrayed by Tony Ganios) was one of Colonel Stuart's group of mercenaries in Die Hard 2.
Baker and his fellow comrade Thompson, who disguised themselves as airport maintenance workers, arrived at Hidey Lake Community Church near the airport and had the church's custodian let them inside so they can check out their equipment. As the custodian admitted he feels at the lost with that the church is on the verge of being closed, Baker let out an appropriate response and killed the custodian. Then he and Thompson had cleared the church to make space for the airport's makeshift control room so they can hack Dulles airport's control tower.
Later that night, he was patrolling the church when John McClane and Dulles chief engineer Leslie Barnes found the church. Then Baker heard McClane's beeper go off and attacked him. Though Baker proved to be powerful in physical strength during the struggle, McClane was able to grab a nearby icicle near the church's detached garage, and stabbed it through Baker's left eye and into his brain, which killed him almost instantly.
