My success story:
On Crash Site the other night, I was able to kill all 6 players on the Crash Site. I stealth killed two, I am happy I can now use the Nanovision properly now because I was able to locate one other player, I am marking players before going into the crash site, so that I am not caught off guard. I killed two with my MK 60, and punched to death the last one. There was a time in the match that I knew I was not going to survive a fight with three players, so I threw a grenade to the ground and killed all three players. What I like about doing this, you can go back to collect your dog tags to get your kill streaks. Sometimes committing suicide for dog tags is worth it.
