The only two I know for sure are the marine squad and the Dreadnought. The others are educated guesses. I love Dawn of War.
Ahhh, haven't played that in so long, and normally it was on the Orc side, but I know what you mean. I figure they probably had the same scriptwriters and actors as the older Warcraft games (back when it was still single-player, yknow...)

"Silos needed" in C&C was always nice to hear... we got plenty of tiberium, boys, so just keep holding off the enemy until we can crank out a few more of you...

and, for me, an iconic moment of first turning on and loading up a 16 bit machine: a very plain and simple "SECTOR ONE". Telling you ... THE GAME'S STARTED - GET SHOOTING SOME STUFF!
Oh and though it was only expressed in text and an "ooo" sample, Maria / Celes' opera in FF6 must count for something, alongside all the lunacy from Kefka?
