Wait what are you talking about? Highlighting people with supers? Like before they have activated? Why am I not using this thing with my defender?

There are scopes available to Syria and Hakke primaries (I don't know about omolon) that highlight enemy majors and enemy guardians who have their supers. It allows you to know who to throw a suppressor grenade at if they aren't already mid super. It's also funny to just use the supressoron an enemy and then calmly pick them off while they try to use their jump to get away but can't (this usually happens when someone was confidently moving forward with their super).
