Re: Starfleet Marine Corps
In TFF there was a ground force used on Nimbus III who had dark blue trim to the uniforms, rather than the dark green of Security at the time.
Personally I avoid using Marines in my fan fic, as security personnel will be trained well enough to handle just about anything the galaxy has to throw at them. But that's just me.
