The idea of one robot having one (potentially flawed) operator seems exceedingly dated to me. In conjunction with AI and dynamically created battlefield models, we could relegate the human brain into making those decisions that human brain is good at ("that's a terrorist, and that guy is a civilian") and let machines do their job at what they excel at ("let's use drone 17, it has its barrel only 7 degrees away from the target, already moving in the right direction, and can hit it within the next 700 milliseconds").
