Not sure if you read Generation Kill or watched the miniseries, but that is one of the main points. In there, there were two platoon commanders, Lieutenant Fick and Captain America(The book never reveals its name, and I think the series does, but I don't recall at this moment). While Lieutenant Fick was a competent officer that tried to kept the welfare of his troops, he often butted heads with its direct superiors since the order given to him could endanger the lives of his subordinates while not accomplishing nothing of value. In contrast Captain America, was an incompetent officer who gave reckless orders, was ignored by his troops and could have been possibly be charged with war crimes. At the end of the series, when the journalist is interviewing the battalion commander about why Captain America was never disciplined for his actions, the battalion commander answers that the same leeway that he gave to Lieutenant Fick was given to Captain America. In other words if he were to punish Captain America, he should also be punishing Lieutenant Fick. In retrospective is understandable, but when you read or watch it, you wonder why no action is being taken to discipline Captain America and why no one listens to Lieutenant Fick
