They have NV goggles as you do and many things depend on mercs and greyshirts lvl. But yes the AI has uncanny ability to spot mercs or get shots in from long distance with pistol where even 100 marksmanship guy would be able. Hehe SkynetV4 I know the feeling, that has been happening more often now,. Because that I stick to night ops mostly and for that FN-P90 god send tool. By the way if you thought mortar was bad, think what they can do with some of antipersonel sniper rifles. They need just one spotter and BOOM one of the mercs goes down.
