one man army, danger close, comando. ult rifle with noob tube. keep changing to the same cl for more tubes. camp in ground war or demolition. another cl with one man army, cold blood, etc. change to this to avoid killstreaks and continue noob tubeing. EGERVIN add me on ps3. 10th prest legit and over 100 nukes :D hope this helped
