Yesterday we were playing Alam Halfa on hslan. I had put my mines in the passage for the axis tanks and then sat in the 2 Pounder.
First axis tank passes, I spot it with the 2 Pounder and when I pressed "Armour", the tank blew up. I thought I accidentally fired at him with the 2 Pounder and 1-shot him, but later a Kubel came along an also got blown up, but... I wasn't shooting at all! So I think they got killed by my mines, and the game turned the killweapin from mines into the 2 Pounder. Here are the screens. Note how you can see that I make both kills, while my ammo stays the same.
