Tommy Garrison is a character mentioned in Battlefield 4: Countdown to War. He is the son of Captain Roland Garrison whom he admired greatly. When he was a child, Tommy marveled at the USS Valkyrie and the fact that his father was in command of it, inspiring him to eventually join the Marine Corps himself.
While on tour in Afghanistan in 2014, Tommy was put under command of CIA agent Kovic. It was at this time that Tommy had thought about joining the CIA due to the impression Kovic had left on him. Unfortunately, he was killed by an unknown cause during a mission. Since then, his father has had a deep distrust of CIA operatives, with a specific hatred for Kovic, and blames himself for introducing Tommy to the military life.
