Hello, help out here

Hello people im gonna make new account,can u give me all tips to get staff sargent fast ( i mean weapons tactics etc)

use m16 till staff sargent 4??

i agree 50 % with ya Toxin >.< .. but M4A1 is a very good weapon .. a very good burst weapon .. SCAR L is good also .. and other guns like XM8 .. M12s are beasts .. in my condition i says try to get thy M4 at the start .. or K2 ^.^ .. i don't think he'll be good at this game if he keep using SCAR L .. cz it's the easiest weapon to use >.<
