1. Place a player-controllable AMV-7 Marshall in editor
2. Place two other AMV-7s, crewed. One with a "safe" waypoint (so they turn out) and another without
3. Switch to APFSDS rounds
4. Shoot the crew in the vulnerable AMV-7 through the armor (not a direct hit)
Result: APFSDS round goes right through the weak armor, both crewmen die
5. Shoot the crew in the tank, again through the armor and in the same spots as before
Result: APFSDS round goes right through again, but only the gunner dies. Eventually the driver will get out due to damage, unscathed
(Additional) 6. Fill up the passenger compartment and shoot in both cases. None of the passengers will take damage, as they don't "exist" outside of the vehicle, even though the round is supposed to fully penetrate the AMV-7's armor.
