Yeah but in the book he's literally having to ration his drones because he can't figure out how to kill a gorilla any way except suicidally ramming them head-on.
To be fair, he's still his old self with his old human skills only. The only thing is he's faster and can compute better. His skills may not have included military tactics but it took him pretty far!
He had a massive library to learn from. My skills don't include tactics either but he worked on this problem for months and never came up with anything better than a flying headbutt.
