Hi, I'm new....There's my preamble. I've been looking for a new social life, figured "Hey, why not with other Star Wars Fans?" I'm 22, lived in the Valley ,y whole life (12 Houses, Same Vally. I can't wait to meet people and get to know you. Anyway my question (this has bothered me for years), does anyone know what the diffrence between the Black, Grey, and Olive colered Imperial Uniforms? It's driven me crazy!!!
