While serving as Security Chief, Jerry became a war hero during the Shadow War. Jerry himself discovered that telepaths were the Shadows' kryptonite. If not for him, the galaxy would have been wiped out by these ancient marauders. Once the Shadow War was over, Jerry did the right thing and resigned his commission after realising his commanding officer, John Sheridan had become a maniac with a messiah complex. Jerry did what all smart men do, went to work for the private sector, specifically the pharmaceutical companies owned by CEO, William Edgars.
