The President is the Commander-in-Chief of the chain of command in the army. An effective chain of command ensures that the army is prepared for any eventuality. Also, the people holding these important designations have been given individual powers so that there is no ambiguity about the power structure. The different ranks have specific roles and responsibilities. The US army is well structured and one of the best in the world.
