I'm not sure why a military leader would need fangs outside of their alt form.
Probably for the same reason Samurai wore masks with fangs, if I had to guess at it. The point is, you're assuming the fangs evolved with zero reason to so. We don't know if these things evolve at all. The fangs could be their version of cosmetic surgery for all we know. Just something they like that doesn't serve any purpose; an adornment of some sort.
