I subscribed to C2 and I can see the stances Prone, kneeling, and stand up but I do not see or can find how to activate stealth, combat, aware, and safe stance in C2. I tried to key bind the combat stance menu as normal but it was using the grenade feature. i then tried to key bind the combat stance menu to other keys. the menu comes up but I can not scroll through the menu. please help.
