If you are fighting an army in uniforms, your targets have like bull eyes painted on them. But if you look at all the modern conflicts since the viet nam war, how do you tell the difference between a viet peasant and a viet cong, between an afghan villager and a taliban, between a kurd fighter and an ISIS fighter?

I doubt we are that close. Recognizing road signs and making judgement calls on the above are not the same order of magnitude of complexity.

Remotely controlled infantry, that would be more realistic.
