I have a hunch, that I can't prove, but something I've noticed over the most recent scenarios I've played. Most of the time I give my units target orders. If I do that with tanks, they usually fire HE at infantry units. But it seems to me, that if I don't give the target order, it fires MG only at infantry, even though it still has HE shells. Is there some reason behind this? Is it more than a hunch? Unfortunately I have no saves to prove my point, but it is something I have noticed frequently.
