This helps you two ways. Getting a pro perk and levelling you up.


 * One, you have to put a certain perk on ALL your classes. Eventually, it will add up and you will get the perk in about 3-4 games.
 * Two, if your trying to get Danger Close/Cold Blooded pro, put an AT-4 or a Stinger on every class. But to counter that, you might want a gun that is fit for CQB as long as filling your role for warfare.

Over two days, I went up 18 ranks (24-42) just doing that and unlocking challenges. All my perks are pro except Sitrep, Lightweight, OMA, and Last Stand.
