By this time, after having teamed for early work on Key Publications' "Mister Mystery" in 1951 and Standard Comics' "The Unseen" and "Joe Yank" (the latter credited as "Mikeross"), the two began a long career as one of DC Comics' primary war story artists, alongside the likes of Joe Kubert, Russ Heath, and Jerry Grandenetti, beginning with a story each in "All-American Men of War" #6, "Our Army at War" #14, and "Star Spangled War Stories" #13 (all Sept. 1953). For those titles as well as "G.I. Combat" and "Our Fighting Forces", Andru and Esposito drew hundreds of tales of combat under editor and frequent writer Robert Kanigher.
