Famas w/ Silencer (Famas is easy mode and the silencer keeps you stealthy)
Python w/Speed reloader (Best pistol in the game. Always use it)
Ghost Pro/Flak Jacket Pro (On the first round use Flak Jacket, if the enemy team gets a spy plane switch to ghost)
Sleight of Hand Pro
Ninja Pro (Ninja is ESSENTIAL, people will be able to hear your footsteps and easily locate you otherwise)
Frag/Semtex
Stun Grenades
Claymore/Motion sensor
As for perks always run 3/4/5.
So I would suggest like spy plane/RC-XD, counter spy plane, and Napalm strike.
SnD is about intelligence. Just learn the correct opening routes and nadespots and you'll do fine.
