When the High Alert perk is equipped, the player’s vision will pulse when there is an enemy outside their vision who can see them. Thus, enemies won’t be able to sneak up behind you when this perk is being used. This is because as soon as you are in their view, your screen will start pulsing.
Besides this, the perk also marks enemies and their scorestreaks and equipment. This diamond-shaped mark appears on top of the enemy or their equipment when you aim down your sights at them.
