**1. Introduction**

If the qualities required of a leader to be a good commander and a good decision maker remain constant in human history in the face of the complexity of the battle, the leader of tomorrow will have to adapt to the uses of new technologies. This will allow him to be better informed, and consequently to be more reactive in order to keep the initiative in the manoeuvre, but also to carry his action further and delegate certain tasks to the machines he will have at his disposal. Such adaptations are not trivial, because they reconsider the existing military doctrines, and can call into question the very principle of the hierarchy that makes the strength of armies. It is therefore necessary for the military to know how to use these new technologies through training, but also to know how to keep control of the use of new systems integrating a certain form of autonomy. Above all, it is important for the military leader to preserve the very essence of his very identity: to give meaning to military action and command to achieve his goals.
