Great Build For Free-For-all, Search and destroy, and Sabotage!

Ok the other day me and my friend made a build on COD4 and when we tried it out it worked pretty well, I call it
"The Assasin!"

my idea for this build combo was being almost invisible and never turning up on the radar, so basically killing somone with a bunch of people around and them saying "where did he/she go?" and others saying "WTF!?" and you come up behind them and knifing them in the but hole!, and i think its pretty awesome. works great practically everywhere but especially in Free-For-All during those quiet moments, also in Search and Destroy or Sabtoge when you can Disarm or Plant the bomb without the other team noticing untill its too late.

VARIANTS:

1. If your not a Fan of Sub guns, then i came prepared, an AK-47 with a silencer worked out pretty good.
2. For extra sneakiness you can switch out Martyrdom for Dead Silence.
3. i do recommend using Bandolier when you have a Sub Machine gun but you can switch it out for Claymore's (putting them in random doorways or other places where people usually walk by, FTW)
4. The Secondary Weapon is completely optional.
