The Bane are ripping us a new one here. Our attempts to push into the base have been unsuccessful. It's as if the Bane have never ending supply of cannon fodder. We've gotten far enough to determine that reinforcements are primarily coming from the two barracks nearby. We're very low on supplies, but we've also detected signs of explosive materials nearby which could come in handy.
Scout out and see if you can salvage any explosives. Then use them to seal off those barracks doors. Good luck!
