Scrambler is a Tier 3 perk appearing in Call of Duty: Modern Warfare 2 that scrambles the radar of nearby enemies, leaving only static. Enemies that are close to, but not entirely within, the scrambling radius will have their radar appear slightly fuzzy and faded. In multi-tiered structures, this can cause confusion to enemy players, allowing them to be picked off. The radar fading effects can also cover the location and direction of killstreaks, further benefiting the team. However, the perk is known to do more harm than good for the player, given the fact that an enemy player's radar fading out is a clear sign that an enemy is near, which can easily give away the player's position, or at least the player's presence.
