Yes. You certainly can. One thing to keep in mind is that if you feel you can do something, you will. If you don’t, you won’t be able to. In today’s world, morale is a factor that counts a lot in a battle or conflict, even if we have superior weaponry. Why? Beacause you have to be mentally prepared for anything, even climbing Mount Kilimanjaro.
Because your muscles will perform whatever your mind tells them to do. Aside from that, please receive enough instruction. Without training, you have no chance.
