Another idea might be to name them after weapons in CS. Based on overal strength of the weapon or something. (Weapon choices are just examples, I just chose some easy ones for the most part)

Knige Wielder
Glock Holder
Deagle Carrier
TMP User
Pump Shottie Maniac
P90 Soldier
FAMAS Technician
M4A1 Expert
AWP Master

Or of course you can fall back on an actual ranking system used by a police force, or an army somewhere.

I like this, very good.
