The reconnaissance skills in "Call of Duty: Black Ops 6" are very useful skills in the game. If players want to be a pure scout, they need a relatively good skill combination, which can make you become Omniscient, equipped with the Ghost perk in Privilege 1 slot, the Tracker perk in Privilege 2 slot, and the Alert perk in Privilege 3 slot.
How to match the Scout skills in Call of Duty 21 Black Ops 6
A better combination of reconnaissance skills requires equipping the ghost privilege in privilege slot 1, equipping tracker privilege in privilege slot 2, and equipping alert privilege in privilege slot 3.

Combat feats combine with this idea to make it easier to decide from which angle to attack after respawning, and to be able to tell if your cover is exposed by knowing if an enemy has spotted you.
