Cheating

[low_bidder]

OK, we will agree to disagree.
I'm at fault, since communicating a concept is the responsibility of the one attempting to communicate it. I don't feel I avoided an answer, just that I didn't answer well enough for you to understand. Let my try again. Sooner or later, something will go really wrong. Something strange like shooting down a Jabo and having it crash on your A0, killing it. That cascades into missing rally rolls that allow a flank to collapse.
As far as the cheating, there is a long history of it in SP. That is why so many security 'fixes' have been done. I don't understand why some players cheat but I don't have to understand why to be aware of it happening.
Recently I was playing a campaign game against a new opponent. I had just moved a Patton Company (17 tanks) up behind a tree line. I had good scouting behind another treeline about 8 hexes away. There was 1 RRJeeep that I had seen. It was next to a gap in the tree line hidden from the treeline I was behind. I moved a platoon into my treeline to see if I could pot that RRJeep. I was seen and on his turn he potted a Patton. I got no op fire, even though the other 4 tanks had no suppression and the fast moving flag wasn't set. It happens. So the next turn I moved the rest of the tank Company into position. I had LOS to the gap in his treeline AND the tree line it self from over a dozen Pattons, none of them in a fast moving state and with 1 suppression point on maybe 4 of them. Most were high 60's, low 70's experience. So his next turn He popped out from behind that treeline with his RRJeep and killed two more Pattons.
I'm not sure how he did that, but I wasn't interested in playing any more so I surrendered the game and we parted ways. While it isn't impossible that 14 units in good order with clear LOS and decent Experience miss their op fire rolls, that wasn't the only time it had happened.
The traditional solution to "jack in the box" or "pop-up target" tactics is to get enough units in position to op fire so that when jack pops up, he dies. Maybe that has been coded out and I missed the notice. Maybe the bar for op fire was raised. Until I see the notice of that, I assume that somebody has found a new way to cheat.
