Earlier today, I saw 3 AIs running from me, about 150 yards away from me. As soon as I crested the ridge line to look down on them, my character called the contact report; as soon as he did, the AI, facing and running away from me, stopped, turned around, and engaged and killed me instantly. The AI does really odd things, especially in Arma 3, i've noticed.

Arma 3 is a military tactical shooter, not a simulation. In any case, do people seriously not read the comments here? We have a Marine rifleman, Samago, make a remark about it, including a real life application example, yet we still have people saying adamantly how it just won't work because (insert how they don't really know if it works or not, but they've played Arma 2 before so there.)
