MS, CMS, SM and Gunnies are all the shit really... You cant help but respect those guys for what they've done and the time they put in... These guys are up front... Like I said, my dad's good friend was a MS and when we'd hang out on base, he got alot of respect from his fellow soldiers... I think once you get into those three/four groups, its a major accomplishment... Like I said, those guys have YEARS in the military...
