A soldier named Thomas (if this is his first name or his last name is unrevealed) who earned the nickname "Tag-A-Long" when he developed a habit of not only copying whatever Sgt. Rock did, but also followed him into potentially dangerous solo activities during combat. Although Rock frowned upon this behavior, Tag-A-Long usually pulled Rock out of hot water, and usually proved to be an assistance rather than a hindrance.
- In Sgt. Rock: The Lost Battalion #1, Easy Company is joined by a soldier named "Kenny" that they call "Tag" or "Tag Along." In DC Comics Presents Vol 1 10, an amnesiac, time travelling Superman also briefly joined Easy under the name 'Tag-Along', but upon recovering his memory, he faked his own death and discreetly returned to his own time.
- Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
