Look, you've been thoroughly trounced by people, so I'll be nice. "Dark ACU" is going to be a problem to start with. Since most games are green vs tan, black starts to become a problem, what with the whole dark=green and light=tan thing. Aside from that, black sticks out like a sore thumb when everything around you is sand, brown, or green colored in the desert.
Next, the WW2 guns thing is very unnecessary. It always seemed silly to me that teams have to have certain weapons. I'm just fine running an M14 and being the odd duck out. It works for me. Who's to say a Tommy Gun, an MP40, Sten, or WW2 replica sniper rifle isn't some else's cup of tea. Also, can I not use a 1911 if I'm on your team? That's from all the way back in WW1, kiddo.
BTW, I'm kinda fat and it hasn't really hurt me on the field (now smoking, that's another story...).
Overall, you're taking this way to seriously. Chill out and have some fun. It's a game.
