Anyone remember the Ghost Tank series?
As I recall, the storey lines were always the same. Beleagured Allies on their last ammo and strength would be aghast to see an unearthly spectre, a Sherman tank flying Confederate colors that would roll in, slay all the enemy and then disappear.
Wierd, but great artwork and lost of those dramatic "Uuunnh!"s and "Aaaargh!"s spelled out like in the Batman comics.
