I'm sure this is going to cause a few smiles out there, but I can't figure out how to select, aim and release grenades in my PS4 version on this game. I seem to be able to use the left d-pad button and R3 to select after releasing the left d-pad button but I don't know how to get a throw arc to display and then to release the grenade. Yes, I know it is something really stupid OR maybe not. If I do the selection behind cover and no arc display is produced, then hit the fire button, I end up with "unaimed fire " from behind cover and just give away my position. It ain't cool at all playing this game without grenades.
