Marking enemies alerts teammates to their positions; level 1 Hawk-eyed allows both the player and teammates to know where the enemies are for a longer period of time.
Level 2 Hawk-eyed highlights marked enemies in bright red (similarly to how friendly players are highlighted in bright blue or yellow). The highlighted silhouettes are still visible through walls or smoke; this is useful because it can indicate to attentive players whether enemies are lying in wait or distracted through healing or crafting. The silhouettes can be useful for when attempting to shoot through cover or smoke.
Hawk-eyed synergizes with Damage Marker.
