Hello there. I don't suppose you stumbled upon this place by accident. Not many people do.
You can call me the Browncoat EMT.
I'm going to answer a question for you:
What is a Browncoat?
A Browncoat is an avid follower of a show called "Firefly" by Joss Whedon. Never heard of it? I'm not surprised. The show was started and cancelled in 2002. It ran one season with 14 episodes before FOX cancelled it, but did get a follow-up in the form of the movie "Serenity" in 2005.
Browncoats on the show and in the movie were the military for the Independent Faction of outer planets who fought against the Alliance of inner planets. Yeah, it's a space western. Browncoats were modeled after the the South in the Civil War, but only in fighting for their own freedom (no slavery issues to deal with). Browncoats outside of the show/movie are simply huge fans of what it was all about.
