I applaud Feller's service in the Navy. But Warren Spahn, was a war hero. Not for serving, which seems the modern standard; but instead, for his actions in actual combat, on multiple occasions. I saw Spahn pitch about 20 years after World War II, I was a kid and barely knew anything about his baseball records. I had no idea that he'd been in WW II, that he'd fought in WW II. Years later, after I read a bit of his military record, I thought this man has done enough; he has nothing to prove on the baseball field after a Purple Heart and Bronze Star, after fighting in The Battle of the Bulge and at Ludendorff Bridge (think that movie about the bridge at Remagen).
