I’m pretty sure they took word for word Patton’s speech that they used in the opening of the movie “Patton”....
In college, I had a recording of it and would play it every now and then out my window in the “bowl” made by our dorm buildings just for inspiration...
Favorite line: “We’ll go through them like crap through a goose...”
Oh, and Patton was a hero to my mother...who survived Nazi-occupied France during WW II....
