Use of simulation to achieve better results in cyber military training

Military operations always required much coordination to be performed, however, with the technological revolution and the subsequent modernization of military equipment, military actions have become faster and more complex, requiring from the Command and Control (C2) increased agility to obtain awareness situational battlefield. Currently, this agility is being obtained with the increasing use of network computer devices, creating a new cyber battlefield. In this technological scenario, where is C2 entirely operated in cyberspace, how to train military commanders of the future? This paper presents the use of cyber simulators as a tool to train digital combatants. As a case study, we present the Cyber Operations Simulator used by the Brazilian Army in military training, as well as the results of the experience gained by the team of instructors of Electronic Warfare Training Center and developers of simulator during military exercises of cyber operations. The study aims to present advantages, disadvantages and to indicate improvements in the use of simulators for training of cyber military.
