Fuchs:

The author stated the problem the US Army had in a very expressive, pithy way. He said the US Army was a 1914 army fighting against and beside 1918 armies. Those other armies had had time to learn all those lessons and had a greater depth of pre-war small unit leaders to draw from so there would be some left alive to learn and pass on the lessons. According to the book, the US Army didn't. There was a lot covered in the book and it gives a whole lot to think about. If the war had gone on, it seems we wouldn't have done much better and may have done much much worse. The straggling (soldiers going back from the line) problem was getting very bad.

The most surprising thing to me was there was no NCO corp as we would know it.
