Scrambler (perk)

Scrambler is a Tier 3 perk appearing in Call of Duty: Modern Warfare 2 that scrambles the radar of nearby enemies, leaving only white noise. Enemies that are close to, but not entirely within, the scrambling radius will have their radar appear slightly fuzzy and faded. The Pro version of this perk protects players from enemy Claymores by increasing the time between detection and detonation. Using Scrambler may give away your position, however; a player would notice his UAV fading, letting him know that another player is nearby. It is definitely not recommended for the Search and Destroy and Cage Match game modes. The main way to tell the difference between a Counter-UAV and scrambler (Other than hearing your commander yelling "They're jamming our radar!") is that your UAV will fade slowly the closer you get to an enemy, as opposed to counter UAV which simply cuts out the mini-map.

Tactics

 * A major flaw to Scrambler is that an enemy will be aware that a foe is nearby (by the mini map being scrambled) even if the person does not attract attention by shooting.
 * Scrambler is especially useful when an enemy UAV is airborne as it serves as a short range Counter-UAV.
 * When used in multi-story buildings Scrambler will confuse the enemy making them think any enemy is nearby, when in reality they are above or below them.
 * Scrambler makes it harder for a group enemies to coordinate their attack as they cannot see what their comrades are doing on the minimap.
 * Scrambler can also mask the size of an attacking force as nearby attackers will not appear in the minmap when they fire.
 * Strategy wise it may be better for a player to use the "Cold Blooded" perk if they are attempting to use flank an enemy, though nearby enemies will be able to use their minimap, the player will not appear on it when they are using a U.A.V, leading their target to believe that they are safe when in reality they are about to be killed.
 * Scrambler is best used in hardcore modes, where there is no minimap unless a UAV gets called in. Scrambler Pro can be a lifesaver in Hardcore Search and Destroy, where claymores are encountered frequently
