We’d have to set some bounds here. I think one guy would have trouble operating a submarine.
Tanks are typically crewed of course… but in theory, a guy could patiently go around and man every station… I wonder if 100 sufficiently motivated gorillas could damage a tank from the outside.
If you want to consider armaments that are routinely crewed by one guy, a bomber will have the same property of being easily capable of killing all 100 gorillas at the same time that they lack the ability to even try to attack it.
Yah. My main answer is a man on a bicycle with a rifle and a backpack full of bullets. Somehow having a powered vehicle seems against the spirit of the thing, although really is it just a fundamentally silly topic anyway!
I could carry a bicycle, a backpack of bullets, and some kind of rifle… I think it really depends on the specifics of the scenario (how far apart do we start and is it flat ground?)
