Find weapon and perk load out you can play really well with and a find a game type you are good at as well. basically, you have to improve your skills and get more kills than deaths over time.
1. Get One Man Army.
2. Use it, and put it with a Grenade Launcher class.
3. Equip a gun with a Grenade Launcher attachment, and then use it to p00n n00bs.
4. Camp in the corner waiting like a no life for some unfortunate person to walk by.
5. Knife him/her.
6. Get more kills than deaths.
You have to continue to do well in matches. You can do this through Team Deathmatch, Free for All, or Ground War the best (through experience).

Quitting the game will not lower your kill-death ratio at all, the only way would be to die more times than you killed.
it is the difference of kills and deaths. Example 20 and 20 would make u have a 1.00 ratio

id say anything over 1.5 is good that means that every 1.67 kills you die 1 time
kill, death ratio
It is a k/d ratio meaning kill to death ratio. The higher the better. So if you got 15 kills and 5 deaths your k/d would be 3. 3 kills per life.
The highest possible KDR (kill-death ratio) in Black Ops varies for all game modes. The highest possible KDR for one match of team deathmatch is 75 - 0 (75 kills and no deaths).
Check your KDR by going to your combat record, going left to "weapons" and your Kill Death Ratio is listed in one of the columns
It works when you do clan battles via the clan wars arena, if a clan beats another clan in the arena their kill ratio goes up, if they get defeated then their death ratio goes up.
