Dean McCabe is a member of the United States Delta Force.
Dean McCabe was identified in the U.S. / U.K. Motor Neuron Rapidity of Response tests as having extraodrinary reflexes, making him one of the few people who could disarm the CincLock-VII security system.
McCabe and another Delta member, Gregory Farrell, were tasked to lead their teams to Siberia on a mission to liquidate some hostile forces inside a former Soviet missile silo known as Krask-8, with Shane Schofield intended to arrive as backup. While in Siberia, Farrell and McCabe's teams were ambushed by Executive Solutions, and both leaders were decapitated to claim the price on their heads as part of a group of billionaires called Majestic-12s plan. Schofield later finds the bodies when his team arrives in Siberia.
Schofield later took revenge for McCabe and Farrell on Cedric Wexley by crushing his head under a door.
