In this second volume on the Incan army, we will explore its political and administrative organization and the excellent planning that allowed the Incan State to experience internal and external safety. Our main focus, however, will be mainly on the development of wartime technology and the application of advanced concepts and procedures of strategy, tactics and logistics. Although the times were quite different, the Incan army had put many of the activities that correspond to the functional fields of the Joint Chiefs of Staff into practice: personnel, intelligence, instruction, operations and logistics, similar to those of a modern army. For a more in-depth understanding, terms that are compatible with current concepts and military terminology will be used.
