The U.S. military at one point, was aiming to develop high level artificial intelligence for a number of its various weapon systems. It has since changed course, and now primarily relies on controlling various weapon systems, such as aircraft drones, remotely. Projecting human intelligence into weapon systems remotely, where these weapon systems have low level autonomous control, seems like to the way to go, in my opinion. I believe troop casualties can be mitigated by adopting the principle of sending remote drones into highly dangerous and unpredictable scenarios, for reconnaissance, and/or to subdue the enemy, so that our troops can more easily gain control of the situation, with limited casualties. For example, squads could travel around with land based drones (operated remotely by the squads) which scout out dangerous streets, or do particularly dangerous house to house searches, to obtain intelligence and largely pacify the situations. Squad members could then move in afterwards, and fully take control.
Manned submarines could carry drones that they use to engage ships and enemy submarines, in scenarios never before conceived. For example, instead of shooting out torpedoes, submarines could shoot out drones, which could closely shadow an enemy vessel for intelligence, and destroy it at will.
The use of drone technology, can open up new, effective, and exciting ways to engage in combat, and increase U.S. superiority.
