The AI here is too stupid. First, their aim is terrible; It's hard to hit a player even when they're standing still up close. Second, their vision is really poor—they should be able to see players through small gaps, but they can’t. Players can detect AI hiding in the grass, but the AI can’t detect players doing the same. Also, AI reactions are like those of elderly people, while a real professional soldier reacts in 0.1 to 0.2 seconds—they’re way worse.

!!!!!! I know some players might not like this high difficulty, so you could set several difficulty levels: easy, medium, unlimited!!!!!!!
