Interestingly enough, "I was an Army Cook" and "I Was an Army Grave Digger "were co-written by the same pair of authors. Which makes me wonder about the ingredients of the Chef's Special Stew.
The fact that we've yet to see "I Was a Halftrack Gunner" in bookstores might also be a clue as to how vulnerable these guys were. And to how so few of them survived the war.
