I remember one time, just once, on a round in that map I saw the doors at the bunker cp were open...  If I'm remembering it correctly, there was just a small space behind it, it was a "dead end" into the rest of the hill that the structure is built on.  I've tried using every type of explosive including the AT-ST.  I even tried punching random keys while I was in the AT-ST while facing the bunker door.  Han Solo claiming "the Rebels are fleeing into the woods" anyone?  Anyway I gave up after what must have been a good 45 minutes of messing with it.  I'd still like to know what to do as it adds a tad bit more cover when defending it.

Yes but really the question is... will you be able to destroy the AT-ST with sticks and stones? ;p
