Commonwealth Bank
The front of the bank is defended by a small group of raiders and a single turret. Once these are taken care of, the vantage point is accessed by using the elevator by the entrance. When inside the building, taking the elevator next to the one you exit will lead you to the roof of the bank, where you can place the MILA. Once this is done, return to Tinker Tom for a reward and a new assignment.
