Although this Marine’s act of brutality does not actually harm the enemy, since the Japanese soldier is already dead—unlike in the previous episode, in which a Marine ignored the enemy’s suffering—it does reveal how common the sight of death has become to these soldiers, who no longer recognize it as anything out of the ordinary. Sledge’s temptation to collect a gold tooth also shows how easy it is for
anyone to fall prey to brutality—even Sledge, who was initially revolted by this very practice. At the same time, Doc’s intervention highlights the intense networks of solidarity that exist among Marines. Doc does not want to appear condescending toward Sledge, but wants his friend to maintain his sanity and his capacity to reason morally.
