The blood that Starfleet has spilled on hundreds of worlds, in hundreds of conflicts. Everyone knows it, so much so that the term 'Red Shirt' has come to mean you've got a less than 50% chance of surviving any deployment. Every Cadet knows it, most fear it, but the day I put on the Red for the first time, it was the proudest day of my life. Yeah it's dangerous. Yeah a lot of us don't come back. Despite that we're all ready to do it again, and again, and again. We know all the stories, all the jokes, we've heard what others think it means to be a Red Shirt...

It comes with the uniform." - Lt. Jason Malcolm Hendorff; Chief of Security, USS Enterprise NCC-1701, KIA
