What it does

Reduce the effect of enemy Tacticals.

02

Where it sits in the unlock curve

Slot three holds the late unlocks, with the final Perk in the game not available until level 36.

03

How to choose it

Perk effects change between Call of Duty entries, so a Perk that solved a problem in an earlier game may behave differently here. Test it in the firing range against the problem you actually have, rather than taking a tier list as settled.
