i would just try to run around a lot and go straight to where the enmies start. put UAV jammer and dead silence on so you can sprint and not be heard. you obviously need a silenced gun (prefferbly SMG) and a silenced pistol. i would also use the 3 frags or stuns perk to help injure or slow down the enemy. it can be done well, you just have to keep moving around and try and predict where the enmies will be when they start. thats how i have become a successful ninja in S&D.
Ya, thats what I would do
