The statistics are very interesting though. In this article someone has actually gone to the trouble of crunching the numbers. In the original series there were 59 crew member deaths, which is approximately 13.7% of a total crew of 430. With that mortality rate it makes you wonder why anyone signed up, doesn't it!
Of those deaths, six were yellowshirts, five were blueshirts, four wore engineering smocks, and a whopping 43 were redshirts. That's 73% people! Poor bastards didn't really stand a chance.
The redshirts deserve to be acknowledged for their sacrifices. It might be long overdue, but finally this injustice has been righted. Jonathan Coulton, the man who penned such classics as Tom Cruise Crazy and Code Monkey has written this song dedicated to the brave, noble redshirts who died in defence of The Federation.
Your sacrifices will never be forgotten, Ensign Expendable. It's thanks to you The Federation continues to survive.
