Many reasons: 1. In the medieval period military leaders had to raise their helmet's visor to address their troops properly, this gesture was continued even after the helmets that made it necessary were gone. 2. Before radio equipment messengers would come to attention when delivering a message and the salute evolved from the ceremonial method of passing a message to an officer, holding the hand with the message up at eye height to show that the messenger had something for him then bringing up the empty hand again after it had been taken to show he had nothing more to pass on, a procedure from the battlefield where the man may not have been heard above musket volleys and cannon fire and had to be more visual. 3. It was also used to show that a soldier was unarmed in the presence of his superior officer.
