I believe, perhaps the Chiefs of the Army, Navy, and the Air Force need not interact in times of external security considerations. Consider a scenario, where a two front war is being fought. The air force, navy and army commanders of, the two fronts, perhaps the Western Command and Eastern Command, should interact and cooperate with their fellow commanders in the respective fronts. One defense chief of a front, should not make decisions for the other defense chiefs of the same front. There should be consensus in military operations, and most importantly, integration. The chiefs of the various defense fronts, must work for a holistic military solution, rather than individual force considerations. For example, if a certain army unit type is not in the scenario of hostilities, the air force can act, and the navy, keeping this in consideration. The army, navy and air force national chiefs are important, in such a system. The front commanders report in detail to their chiefs. The chiefs regard the reports closely. If required, their office works closely with the front commanders, but not the chiefs, directly. The office of the national chiefs, and the front commanders are responsible to the national chief, who does not take personal initiative in operations. He is the person who takes responsibility for his service arm's result of operations. He then briefs the civilian authority in the government, concerned. Is my suggestion feasible? I will add to this post, later.
