Bomb Squad (perk)

Bomb Squad is a Tier One Perk in Call of Duty 4: Modern Warfare and in Call of Duty: World at War that gives a player the ability to see enemy explosives such as C4 packs,  Claymore mines,  Bouncing Betties and  Satchel Charges. Enemy explosives are indicated by a skull or explosion symbol.

This is a very useful perk as it allows players to successfully take out and detonate enemy explosives before the explosives can kill teammates. It is more effective on game modes where a well placed explosive can guarantee a team's defeat (such as Search and Destroy), but less effective in "run and gun" game modes (such as Team Deathmatch), where explosives are less effective in these modes. It is unpopular with players because the other first tier perks are useful in more game modes. This perk can be combined with the third tier perk Deep Impact to shoot enemy explosives through walls. It is also helpful in stealth classes as it warns the player of any claymores, bouncing betties, etc. when they are sneaking up behind an enemy.

Call of Duty: World at War
This perk is a must due to the extremely small size of the Bouncing Betties. If you come across one and you have the perk activated, it is easy to quickly destroy it and move on into attacking the enemy. This perk is also extremely useful in Search and Destroy matches, as BBs and Satchel Charges will often be planted around the objectives and will be quickly detonated if not taken out. If a player has the perk on, that player can come and destroy the explosives, giving enough time for others to plant the bomb and take their defensive positions for a safe victory.
