Federation Starfleet ranks (2270s-2350s)

The late 2270s saw yet another major change in uniform style and rank. The uniform consisted of a maroon jacket with a frontal placket that was affixed in place by a shoulder strap that denoted department and rank. Rank was determined by a pin, that varied with each rank. The rank pin was also affixed to a specific loaction on the sleeve of the jacket, next to another strap that had pins that denoted years of service within Starfleet. This rank system stayed in use until the 2350s when Starfleet retired the uniform style in favor of a utilitarian one piece jumpsuit.
