Redshirts on Trek. They were the jobbers of sci-fi. If you needed someone to die to make the brain sucking alien look strong, they were your go-to guys. I like to think that Starfleet Academy had a training program just for those guys. The first class taught them that if you ever beamed down to a planet and saw a strange glowing object floating above the ground, don't let the science officer know, just slowly walk towards it mouth agape, always prepared to say "my god, Captain....it's....beautiful" before you try to touch it and it drains your life energy from your body.
