G.I. Combat #138 (On Sale: August 14, 1969) has a cover by Joe Kubert.
We began with The Haunted Tank in "The Losers" by Robert Kanigher and Russ Heath. This is the first story of the Losers, the cover calls them the Born Losers, who would eventually take over Our Fighting Forces. The team consisted of Captain Storm, Johnny Cloud, Gunner and Sarge. This Losers origin story was reprinted in Showcase Presents: Haunted Tank Vol. 2 TPB.
The back-up story "Bright Banner" was drawn by George Evans.
