U.S. Army". Two subsequent present-day episodes found Rock tracking a Satanic figure that he believed was Adolf Hitler (B&B #108) and an Easy Company "ghost" that he'd been ordered to execute at the Battle of the Bulge (B&B #117). In the bizarre Brave & the Bold #124, Bob Haney and Jim Aparo actually guest-starred as Rock and Batman trailed a terrorist organization called the 1000. Following this, he appeared as a general and a Chief of Staff for Lex Luthor's administration. However, Frank Rock was involved with an incarnation of the Suicide Squad. At the end of the title, he peels off a mask and walks away from the team, while his companion "Bulldozer", assumed to be the original, stands up from his wheelchair, comments on how it was good to feel young again, and also walks away. Whether this was the real Frank Rock in disguise or an impostor is unknown; the series concludes with the line "Frank Rock died in 1945".

He and Easy Company live only, and will eventually die, to the last man, in World War II. The first use of the Rock character after the demise of the series was an issue of Swamp Thing, six months after the release of Sgt. Rock #422. The story was set in May 1945, intimating that Sgt. Rock had survived the war in Europe and raised the question of whether Rock transferred to the Pacific theatre. During the Imperiex War set in the early 2000s, Rock acted as head of the Joint Chiefs, volunteering for the suicide mission to pilot a plane loaded with nuclear bombs as part of a plan to crack Imperiex Prime's armor and drain his
