Use your USP the first gun you'll ever get... Then conserve your exp to about 350 and buy the G36... Then conserve again to about 1200 for the FAMAS... After that conserve again 5000 for the FN SCAR... The Scar is very useful... fast rate of fire, fast reload time, and a pretty large magazine that can hold up to 150 ammo... repair if necessary and stay alive...
