In war, what purpose does morality serve?

There is no absolute morality. Morality is a luxury that can get you killed. Morality is a good thing in a civilized world but not in the jungle. In the jungle, its kill or be killed. The higher the moral plain you function on the more casualties you will suffer and the more impossible victory becomes. When our leadership call for morality they are saying we don’t want to win. Or they are saying winning is impossible. Maintaining the status quo is the only option.
