I'm on 5th mission of russian campaign (Crossing the Dniepr), and the US tank from screenshot below basically halted my entire force. It was well hidden between two houses with a perfect view down the road I had to advance. I suspected that crossroad was well guarded, so I first shelled that area with 155mm heavily. I don't know if I hit it then, but that whole area took a lot of damage. After that, I sent a t-90 down the road and it got hit immediately and burst into flames. After that, I used infantry squads to spot it from the flank because I knew the approximate location.
After pinpointing the exact location, I was able to call in artillery (point target) with my forward observers in church tower (they couldn't see the tank, but i was able to place a target on it). The US tank took several direct 155mm and 203mm hits (visible on screenshots) and all buildings around it were destroyed. I also used all my heavy helicopter ordnance on this guy (none of the guided missles were able to hit it, they all hit the ground or trees 30m away from the tank?!). He still managed to survive somehow.
At this point, I was basically out of heavy air and artillery rounds, so I sent two t-90s in hope they would spot him first, but it turned to catastrophe with both my tanks destroyed without even firing.
How can this thing survive multiple 203mm rounds? Also, why did all my helicopter guided missles miss (even after artillery destroyed surrounding vegetation and buildings)? Also, briefing mentions precision artillery strikes, but all I have is point/area/linear with general/personell options. Are there guided artillery rounds in this game? Any tips on this situation?
