in a "flashback" style. A Viet Nam soldier by the name of Adam Rock appears in Swamp Thing #16 (May 1975), though it is never specifically stated if he is intended to be a relative of Frank Rock. DC Comics published Sgt. Rock: The Lost Battalion, written and drawn by William Tucci, starting in November 2008. The story places Rock and Easy Company with the 1st Battalion, 141st Infantry, which was surrounded by German forces in the Vosges Mountains on October 24, 1944, and eventually rescued by the Japanese-American 442nd Regimental Combat Team.

Rock: The Lost Battalion Rock's unit is still referred to as "Easy Company" but is of the 141st Infantry Regiment. However, in the closing pages of the last issue, the narration states that, following the end of the story, "as usual, Sgt. Rock's 'Combat-Happy Joes' moved out to
