How does the LR Detector perk work in MW3?

Stay alert!

The perk system has been entirely revamped with the arrival of Modern Warfare 3, introducing a wide range of new perks, including LR Detector. However, the in-game description of the LR Detector perk is still unclear to many.

The LR Detector works slightly similarly to the High Alert perk from Modern Warfare 2, as it triggers a visual notification when someone is pointing a laser or red dot sight toward your operator. This enables you to stay alert of enemies who are hiding from your view or targeting you from a far range with a sniper rifle. On top of that, it warns about nearby Radiation Sources.

The High Alert perk in Modern Warfare 2 was more powerful than the LR Detector perk in Modern Warfare 3, as it could make a yellow outline appear on the player’s HUD when an enemy outside their view looked at them, no matter if they had a laser or red dot sight. In addition, the High Alert perk helped players to hear the footsteps of enemies who activated Dead Silence in Call of Duty: Warzone. Therefore, I feel the LR Detector perk in Modern Warfare 3 is a significant downgrade.
