Mines on hilll 243 Soviet mission - how?

[wolfweb]

Soviet campaign - I've had to clear the trenches, capture the church, capture hill 243 and now my mission is to hold hill 243.

I've found some anti-personnel mines and can lay them no problem, just select mine from the use action menu.

However I think I need some mines for the waves of tanks, I can't seem to stop them with the handful of men I have left.

I found some mines on the top of the hill in the middle under the camo net. But I can't seem to use them in the same way as I use other mines. They don't look much like mines, they look more like mortar bombs, but the mouseover popup says "mines" - see image:



How can I use these mines? All I can do with them is pick them up or drop them, there is no mine in the action menu when equipped with them. Am I missing something? Where are the antitank mines then?

Thanks!
