 Commander-in-Chief is on the list, but I want to add to my answer on that, that Congress has substantial authority in the national security realm. Congress declares war, it raises armies, it has power over the purse. So that may be viewed as not really in that core set of functions, which nobody has any power but the President over. Yes, I think that there may be some aspects, like directing troops on the field, in which the President's power is completely unreviewable.
