Objective
Attacking team

Eliminate all enemies, or destroy an objective. Plant the bomb on one of two objectives, indicated by an A or B, then defend it until there is not enough time to defuse it. Note that the bomb can kill any nearby enemies, and the person who planted it.

Defending team

Eliminate all enemies, or defuse a planted bomb. Remember that it takes 5 seconds to defuse the bomb on stock settings. Even if all enemies are eliminated after the bomb is armed, the attackers can still win the round if the bomb explodes. Victory is achieved as soon as the bomb is defused regardless of how many attackers are still alive. Defusing the bomb is very loud, and can be heard from quite a distance. If no bomb sites are destroyed, the defending team wins if the time limit is reached regardless of how many defenders versus attackers are left alive.

Glitches
 * A glitch that can occur is when one is planting the bomb, and a stun grenade goes off nearby, the player will have planted the bomb and yet still be "planting it". Though they are able to walk about, they are unable to use their weapons.


 * By holding left trigger while interacting with the bomb, the player will instantly throw a C4 immediately after the bomb has been planted or defused. However, this C4 cannot be detonated or shot, causing many players to label it a "fake C4".
 * A glitch similar to the "stun grenade glitch" can be achieved by placing a claymore at the bomb site then immediately planting the bomb, this should allow the player to walk around with the bomb in hand while not arming it.



Strategy for Defense

 * One strategy is to Ninja Defuse which is done by camping near one of the targets while staying hidden, then crouching or going prone behind the bomb planter, knifing him/her and defusing the bomb immediately after it is planted.
 * Proximity detonation and remote detonation explosives can be useful for protecting targets.
 * In Call of Duty 4, it is possible to throw C4 under the objective but still have it exposed on all sides so that it can kill anyone near the objective.
 * In World at War, it is possible to leave a Satchel Charge on top of the target and blow up the bomb planter.

Strategy for Offense

 * Planting C4 on the crate after planting the bomb is a good anti-bomb defuser tactic. Simply plant it and hide somewhere within the audible range of the bomb. A direct line of sight is not necessary as long as defusing can be heard. Most players will not notice the C4 and even more experienced players will often think it is the "fake C4" that the bomb planter can throw. Even if an enemy player realizes it is real C4 they will usually try to blow it up, giving away their position. Also, if there are many enemy players still alive, they will oftentimes cluster around the bomb defuser, allowing for several kills at once with a well-timed detonation.
 * When a bomb planter goes to a target, have 1 or 2 people check the area around them for enemies, especially if it is in a building.
 * When moving toward a target, be on the lookout for enemy explosives. Blowing them up can give away a player's position, so it is advisable to maneuver around them if at all possible. When doing so, players should take care to warn their teammates of the location of enemy explosives as to prevent any avoidable casualties.
 * After planting, a good strategy to defend it, without being at the actual bombsite, is to leave the building/hide behind cover nearby, and using a headset, the player can easily hear the bomb starting to be defused, allowing the player to simply break out of cover and kill the defuser.

Trivia

 * This mode becomes very popular on double XP weeks.
 * In Call of Duty 4: Modern Warfare, the crates where the bomb needs to be planted on seem to contain FIM-92 Stingers. The same thing goes with Sabotage.
 * In Call of Duty: World at War, the target looks like the supply drop which contains satchel charges in Blowtorch and Corkscrew.
 * The game mode is very popular because of the seriousness taken by everyone given only one life and the fact that you can earn a lot of XP from a match.
 * In Modern Warfare 2, defusing and planting the bomb shows the player repeatedly hitting the 2 & 3 keys. After planting the bomb, the player tosses it on the ground. Also after defusing the bomb, the player taps the case twice and keeps it.
 * Many people use the C4 Glitch, planting the C4 on the Bomb Crate after the bomb has been planted. It is very easy to do and widely known among Search and Destroy players.
