And that you think that his is a particularly meaningful or cogent statement is why you are unfit for a command, which fortunately, you will never have. Battlefield commanders must make life-and-death decisions under great pressure and often with little time to reflect, with often arbitrary and conflicting rules and rules that do not clearly apply to the circumstances, always with mission accomplishment and safety of his forces foremost in his mind. You, in your barracks lawyer mentality put a value on neither lives of his men, nor mission accomplishment, which are among a commanders most sacred duties.
You are quite simply dead wrong about the bit about protecting the lives of the men under his command not being part of his duties. It is one of his foremost obligations, which, in your ignorance of command responsibility and the traditions of American military you overlook.
