There are many types of kill streak rewards in "Call of Duty: Black Ops 6". When you kill multiple enemies, you can get a kill streak reward, and the anti-reconnaissance drone is one of them. As a bonus, the role of the counter-reconnaissance drone is to interfere with the enemy's mini-map to prevent the enemy from locating your teammates.
What is the use of the anti-reconnaissance drone in Call of Duty 21 Black Ops 6
The role of anti-reconnaissance drones is exactly the opposite of that of unmanned reconnaissance drones. Not only does it not reveal enemy locations, it also prevents them from locating your team by interfering with their minimap.
Counter-reconnaissance drones also completely negate the effects of active drones or HARPs.
