Yes kevin. Come out of the trench with your hands up and surrender. Believe it or not, the vast majority of soldiers are not mindless butchers who take delight in killing. But since you've never been there, how would you know that?
Under the rules of war, you do not shoot a man who is trying to surrender. Once the soldiers in the trenches saw what was happening, all they had to do was surrender when they saw the bulldozers headed their way. That they chose to stay in the trenches or to retreat is not the fault of the US Army. they COULD have surrendered.
As Big Mick or Norton1 will tell you, the war lovers and kill-crazy types are not to well liked by the other troops, most of whom simply want to get the job done and go home.
