and mainly play warzone i can explain this for you
there is an armor mod called “Advanced Sensors”
it is a common rarity and level 5 REQ (all armor mods are level 5)
i love using it over ANY OTHER armor mod
reason:
it makes you invisible on radar while walking/jumping/clambering
the only time you appear is if you shoot or run or boost
combine this with a silenced weapon and you will never show up on anyone’s radar unless you are running/boosting
i know it increases the range from 25M to 40M in warzone and i believe you can see enemies even when they are crouching
it is a very good armor mod, almost too good.
