From what I understand if they would have let the footsoldiers make some decisions things might have been different on all fronts. The soldiers were brave men, whether German, Russian, American, English or from other countries. Many sacrifices were made and so many unappreciated.
On the other hand, most of the footsoldiers were peaceloving men and would have much rather been home with wives, parents, and children. God rest their souls.
