This may already be in the game in some way but if so it needs improvement. from my experience, I have noticed AI shooting me behind and inside foliage when they obviously shouldn’t be able to see me because I couldn’t see them. But as stated in the title I fully believe this game needs a foliage concealment system of some kind preferably similar to Arma! So the AI can behave more realistically in combat encounters so you aren’t shot when the AI can’t see you and you can’t see them. or so that you can use concealment to your advantage by hiding in a bush, grass, or some other kind of foliage causing you to be harder to detect depending on certain factors like distance, stance, and noise (if you’re shooting or moving).
I’d love to hear thoughts and opinions on this and if you guys have any experience with issues related to this or if you guys have anything, in general, to add to this.
