Domination

Domination is a multiplayer game mode featured in Call of Duty 4: Modern Warfare, Call of Duty: World at War, and Modern Warfare 2. There are three flags scattered about the map that begin as neutral. Teams gain points by capturing these flags. Domination is a very popular game mode thanks to its high rewards and tactical game-play.

Points to win: 200

Hold a flag: 1 point per flag every 5 seconds

There is no time limit.

In domination, there are three ways to gain xp:

Kill: 50 EXP (100 if you or the victim was capturing a flag or if they were defending close to a flag the opposing team owned).
Assist: 10 EXP
Capture a flag: 150 EXP
Kill an attacker (Defender +50 xp)
Kill a defender (Attacker +50 xp)
Modern Warfare 2 Domination is a bit different. Now, you get 150 points for capturing a flag. You also receive the points if you help to capture a flag. Other than that, it is basically the same. You get the same points for killing an enemy or getting an assist as in Team Deathmatch. But if you kill an enemy trying to take a flag, or pretty much anything dealing with you, the enemy, and the flag, you will get a bonus such as "Offense" (Kill a flag defender) and "Defense" (Kill a flag taker). Unlike other game modes, or previous Call of Duty titles, there are no challenges linked to winning this game mode in Modern Warfare 2.

Tips

Coordinate. In domination, it is important to make sure that your team keeps all flags that they capture. Instead of having everyone run around going from flag to flag as it seems fit, have one or two players stay with each flag that your team captures. This way, your team's flags are protected, and you can still move about and capture neutral and enemy-controlled flags.
Only control what is Needed! If your team is behind you, you can try to capture all of the flags. But if your team is near the enemy's score, it would be best to have 2 flags captured instead of 3. If all 3 are captured, the enemy team will start spawning anywhere on to map. This will make it harder for you to find them, if you capture 2 flags, you will know where the enemy is going to spawn. This might cause some or all of the opposing team to quit. You can get a high kill streak by having 2 flags captured. This is possible by maps like Highrise where the enemy team will get spawn trapped (where they only spawn at their flag). The only way the enemy team will be able to capture other flags is if they can break through your spawn trap. Or if your team captures all of the flags.
This is one of the main non-team death match modes where this game mode is played only for kills.
Planting C4 on a captured flag then blowing it up when an enemy tries to overtake it is a good strategy.
It is advisable when capturing a flag to have 2 or more teammates covering you, rather than you being there alone, or them being with you, since you all can get killed if you are at the flag at the same time, and your allies will know where the enemy is if you get killed, and they will go and replace you and kill the enemy.
It is very important to know what your team is doing, since occasionally an enemy will capture a flag after a teammate just ran 5 meters away from it, intent on getting kills without realizing that there is a free kill right under their noses.
A good kit for setting up a trap involves using a smoke grenade, a claymore and a fast mobility weapon. Arrive at the flag and plant the smoke, then plant the claymore and run off and wait nearby. Enemies can't resist an easy target, but they'll be in for a surprise. Beware that only one of theses grenades you can carry unless using Scavenger and opponents probably won't fall for the same trick.
