Yes, I understand the old contacts situation.
I was still confused by my units actually taking fire from a '?' or even multiple ones while they sit there or self-retreat instead of firing back. I realize the AI won't area fire on it's own but they do seem more responsive in returning fire on Veteran since enemies are identified faster.
One example would be a static, hull down T-54 that was firing on my M1A1s. I would set a narrow fire arc for it, set my platoon of M1s on Hunt for a short distance into view, tried both buttoned and unbuttoned, and they would proceed to get fired on from the T-54 and hit often enough without ever returning fire. Obviously there was LOS from it to the M1s but they would never see it. The only reason I knew what it was is because I had it under observation from an HQ unit further back and even that would switch from ID'd to question mark and back quite often. I lost an M1, another immobilized, and a third had it's FC system knocked out due to all the fire I was taking from it. That was after 3 attempts to move up as a platoon & get a shot. They did manage to knock out a mobile T-55 that was much further away right off the bat, but the closer static tank was just hammering away the whole time.
Anyway, thanks for the reply. It just baffles me and I wanted to see what others thought.
