Maybe if it was Bot vs Human. In reality, it will be Bot + Human vs Human.

Bot+Human? You're describing a drone, and you're right, it works great. Might work better if they could upgrade the optics a few notches, but I'm sure that's already in the works.

A drone is one possible implementation, but I was thinking more of a standard infantryman accompanied by two or three bots.

Leave the strategic decisions to the commanders, the tactical to the infantryman, and the split-second firefighting to the robots.

Yes, I think Bot-assisted humans would be far more effective than either one alone. Imagine the cunning of a human brain, enhanced with the senses and reflexes of robotics.
