This happened in my game, guess I might as well post it here. Is this supposed to happen? I don't think Soviets are supposed to have control over Marder 3's.
Here's what happened: The AI was using a bergetiger to ressurect dead vehicles and i didnt even notice for a while but i was getting tons of XP for enemy tanks getting destroyed which I thought was friendly fire on the german side, but then I realized that this tank giving me XP was a PE Marder 3.
