Kill streaks!

Try out the specialist kill streaks in MW3 its very rewarding. It basically turns you super human once you unlock all the perks, which leads to some amazing clips and fun times. I think it is the best kill streaks for any one loves to run and gun. Also when using the specialist streak you can earn the M.O.A.B more easily since your gun is buffed along with yourself a lot more then with other kill streaks.
