Concept for two star trek uniforms.
The Pilot uniform is intended to be used by pilots flying my Firebat Interceptor: [link]
I got the inspiration to make a tactical marine-like uniform/armor after watching TNG episode "Chain of Command". In this episode, Picard, Worf and Dr. Crusher are sent on a secret tactical mission. While the episode is very good, one of its premises seems flawed to me. It seems very unlikely that any current navy or airforce ship captain and ship doctor would be sent on such a mission.
The script try's to justify it by conveniently making each member of the party a "specialist" in one required area of the mission, but the reality is they were sent because they are the lead characters in the show. This made me think: does the Fed have any type of Special Operations Force (similar to today's US Navy Seals, or UK's Special Air Service)?
