[Wdll]

I rarely feel the need to use it, so I found myself not doing it right.
I want to set up some of my atgm to fire only at MBTs, no matter what direction they come from (imagine a scenario where the enemy has surrounded you or whatever.

I end up having an atgm unit not firing at anything automatically.

I won't bother you with what I do because obviously I do something wrong, can someone please give me detail instructions of how to do it?
