Im sure it was a one in a billion thing
In the original SP, I once lost a T34 to a stray 81mm mortar shell. Not even a barrage of the things either. Just a single mortar, firing a single shell.
Never seen anything like it since, and that was years ago. I joked that it must have fallen down the hatch or something. i just attract weird luck.
What was maddening about that Korea scenario was that it seemed whenever the planes did shoot up the enemy, they'd insist on only targeting the exact hex they were aimed at, even if that only held 2 infantry guys, with a T34 within a hex or two because it had moved. But when they decided to strafe my guys instead, they'd meticulously pick out the best targets
Maybe they were communist sympathizers.
