The following page details the ranks of the NMX.

Enlisted troops wear a rank pin over their left chest pocket and (humanoid) officers wear shoulderboards. NMX Officers are mostly Mishhuvurthyar and the NMX Enlisted are mostly Nekovalkyrja. The rank system is fairly simple, with two base ranks for officers and two for enlisted; each base rank has three tiers. The officer ranks are organizational and the enlisted ranks are experience/prowess based.

The NMX also has an abbreviation for Zombies: ZF. For obvious reasons, Zombies do not wear ranks (or often not even uniforms) and are not eligible for promotions.
