I actually like this scene quite a bit. It shows the "havoc of war and the battle's confusion," as our National Anthem puts it—the confusion is part of the point. And whether or not you care for Giuffré's acting, you can appreciate his situation as an honorable soldier forced to send the men in his command out to be slaughtered, over and over. It also shows an unexpected side of Blondie's character, as he shows a glimmer of pity, first for the senseless killing and then for the wounded and dying Captain, whom he advises to "Keep your ears open" just before he departs to blow up the bridge. The payoff comes when we see the smile on the Captain's face as he hears the explosion, and dies a happy man.
