Usually get a noob-ish weapon like the famas silencer (or reflex/red dot), then use like nova 6 gas and claymores, secondary should be like a m72 or rpg (pistol if good at SC)
perks, any tier 1 perk that can get pro easily Lightweight?, 2 tier hardened is good for any type of gameplay or warlord, and hacker wont get you killed by c4 and claymore etc. (and when pro will make you not be seen on motion sensor!) and um... dont put emblems on your gun or that crap, KEEP YOUR CASH! lmao, and killstreaks, rc-xd/spy plane sam turret, napalm or CP

goodluck!
P.s. make it like headquarters, you get points even if you die (if you have the headquarters!)
