War is but a matter of logistics, men, and morale, and you are the master of all three.
You are a general, a warrior and leader rolled in one you know the best strategies to take in war and can make plans that make those of your opponents look stupid by comparison.
You would be able to gather a ludicrous amount of resources from a barren desert, and then send those supplies through a bandit infested waste without being molested, and then turn around and convince your mutining troops to march to certain doom for you.
Your charisma can only be described as a thing of legend. Able to make men fight for you to their very last breath as though you were their father. Or able to make men fear you as though you were the devil himself. You can turn even the most spineless of weaklings into a hardened badass who can fight anything the world throws at them, and that is only the beginning of your army as they grow in strength both in physical, and mental might, the more they fight for you.
If you wish for it, it will only be a matter of time before you inscribe your name into the annals of history alongside those such as Julius Caesar and Alexander the Great.
