Well luckily you have come to the right place! Joystick Riot has just released a new series called Black Op 2 Search and Destroy 4 N00BS! In this series, you can master the art of this gametype by going through each map and looking at the different strategies. Here is an example video of what you will get that features a YouTuber, JahovasWitniss, that has over 400,000 subscribers!
I don't se how hard it is for a team to head to a bomb site to plant, or the other team split up and defend their sites, using guns that work well for certain maps. Attackers don't plant, they don't win, setup shop for victory. Etc
I've been playing S&D the past 4 CoDs and it is by far the easiest game mode out there if you have a decent team even if it's just me alive just play tactical.
