[quote name='Littlefields']I find it kind of hard to believe that Carmine seems to be the only person wearing a helmet in a war. Yeah, I know there's suppositly more that do, but he was literally the only soldier wearing a helmet in the first game.[/quote]
The uniform Carmine wears is the default uniform for all the lower ranked COG members. It's just like regular army fatigues. I believe they're actually called redshirts.
Little ironic that Carmine was the only soldier to wear a helmet and he ended up getting killed. (Helmet blocks your vision and distracts you.) I guess that shit saved him from dying though.
[quote name='Aku']Plus, as much as I like Carmine's design and rather short appearance (Kind of found it funny that he was all "COOOL!

" like a child when he saw Marcus for the first time), I'm really glad all the main characters have there own looks and are not running around with helmets, just like a certion little space marine we all know.[/quote]
All of the characters in Halo's campaign were different and unique, just like in Gears. I know you're talking about multiplayer, but the same could be said about Gears' multiplayer too. You can have 4 Carmines running around or 4 Raams.
