True randuin, you could probably do that, but each race has a counter for a terran stacker. Since they are all on top of each other, a terran player can just use 1 nuke. That should destroy all bunkers in one shot, or at least put them in red. ( i dont remember, rarely have i ever wasted nukes on bunkers...) Protoss could use reavers. The splash would hit all of the bunkers beause they are in such a short area. With zerg you have 2 options. You could either use guardians to take down the bunkers or do it the easier way. Use defilers and plauge those mofos to burning.
