If you were a grunt in any army...

[RottingAwesome]

probably a grunt from mgs.
yes, they're incredibly stupid and seem to only be able to see 10 feet in front of them BUT there's the chance that the player is actually trying to be stealthy and get as few kills as possible (using the tranq or otherwise) so i think i would have a better chance at surviving XD

I always wanted to be a stormtrooper

...HAIL ZEON!
I will follow my orders from Char Aznable and Kycilia Zabi until my mobile suit refuses to function!

 

[Mean Mother Rucker]

Protoss Zealot. I get freaking laser blades on my frickin' arms and can take on a dude in a steel suit with a gun as well as a freak alien, and still look bad-ass even when my ass is handed to me on a silver platter. Also I love fighting up close and personal.

Reliable Excavation Demolitions. The soldiers there fought the Nazis till 1946.

A grunt in any military? Well, I'd have to say the US Marine Corps, Hoorah!

As for fictional I'd have to say the Mobile Infantry from Starship Troopers, the book not the movie. Gotta love power armor and tactical nukes.

Ooorah. Not hoorah, ooorah.

Um, he's a marine. Not Army. Marines say "hoorah", Army says "oorah" or, more commonly "huah"...just a slight change on the pronunciation to diffrentiate themselves from the Marines.

 

[Ben Jamin]

I'd be a Gear. Whats not to love about guns with chainsaws on them?

In real life though I would like to be part of the SAS.
