If by how would I go, you mean how would I die, I would assume with a gun in hand, trying my best to stay alive and help those around me do the same.
If, of course, you mean how I'd do in warfare... honestly, I think I'd be well cut out for it. Stressful, fast-paced situations agree with me. I really just love facing adversity and immediate challenges. Naturally, I don't have any real experience or training, so I don't really know, but still. I'd fight.
