A more fitting word for 'war chief'

Hey guys! I'm asking for help once again ^^; Maybe it's my crazy brain, maybe it's the hour, or maybe I just don't have a wide enough vocabulary, but I cannot think of a better term than 'general' or 'war chief' for the leader of the army in my fictional setting. In this case it's a woman, but this is a position passed down through a familial line. Doesn't matter if it's man or woman, just as long as it's this line. I'm trying to stay away from made up words as much as possible (and the ones I do make up I'm trying to keep to 3 syllables at absolute most). This position is essentially the leader of the entirety of the army and is overarching head (though not directly in control of) the capitol city's police force (called peacekeepers). The familial name is "Canthet."

Any suggestions? I really can't think of anything.

Wow, thanks for all the suggestions! In this culture each child born is given a destiny of sorts, or a job. So in the Canthet line the first born is the leader of the army, second born becomes the Emperor's (or Empress's) personal spy and assassin, third (if they have that many) is given to the priesthood, etc, etc.

Shogun would be proper, I think, if this were taking place where such a word existed. Probably Warlord or Lord Protector. Thanks again for the help!
