I just wanted to mention a brilliant mod I came across. FC3 vets will already have this but for the sake of rookies (like me):
This mod removes ALL icons. You dont see any when you use the binos nor do you see the silly cartoon icons on top of peoples heads. Along with this turn off all the aids like auto-target, threat detector etc.
Just doing this adds SO much more realism and value to this game. Without the cartoon icons you have no idea where the bad guys are and they sneak up on you. This really rachets up the tension.
Im reallly surprised theres no in-game function to disable the cartoon balloons which completely ruin immersion.
Grab it from here, theres different versions:
