... any and all weapons? What military are you talking about? And I really dont think widow or winter soldier or frank really stand a chance. You seem to not mention that batmans greatest strength is his ability to think and react on the fly. He is not only the best detective but also the greatest tactician. Im not saying it would be an easy fight but I think in the end batman would come out on top. But I do value others opinions I just think you kinda rushed this without putting much real thought into it.
