"Big Max" from Our Fighting Forces #153 (DC, 1975) by Jack Kirby and Mike Royer
At 181 issues, Our Fighting Forces was no slouch either, and is best known today as the home of the Losers. This JLA of war comics heroes assembled fighting men from a variety of solo strips - Gunner & Sarge, Johnny Cloud, Capt. Storm - but while their stint went from #123-181 (with an issue of G.I. Combat besides), the only stories that really interest me are Kirby's insane ones from #151 to #162. The Omnibus is awesome. For the rest, there's a Showcase Presents that covers up to issue 150.
