My Dad was a machine gunner in the same outfit as Audi Murphy and he saw lots of action. He never had much good to say about American tankers- although he had great admiration for the Free French tankers. He said whenever they came upon a strong German position the tanks withdrew and the command came Infantry to the front!
One of his jokes was :
" Do you know why a Infantry Man is smarter than a Tanker? ans. Because there aint nothing between his chest and a German bullet but his GI shirt!"
My Dad was awarded a Bronze Star for his bravery near Colmar France for defending a village with just his 1919 Browning and two other GI`s.
He knew what he was talking about. On a side note I showed him my then new 9MM Beretta and told him the Military was switching over to it and replacing the 1911`s . He snorted and called the 9mm "sissy guns" and swore they would regret the change and someday go back to .45 cal. I really miss that man!
