Broken Monorail
To reach your location, you must first go inside the Haymarket Mall and fight your way through both raiders and a few turrets. Keep on climbing up until you reach the roof. Beware, once you exit into the roof, a Deathclaw will be waiting for you. Once the deathclaw is killed, look around the building until you see a monorail train hanging underneath the bridge. In order to enter the train, simply follow the catwalk down. Carefully walk across the monorail train until you reach the end. There you should see a plank and place the location where you place your MLA. Once this is done, return to Tinker Tom for a reward and a new assignment.

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 the Sole Survivor exits will lead to the roof of the bank, where one can place the MILA. Once this is done, return to Tinker Tom for a reward and a new assignment.

Camp Kendall
This location is defended by a group of Raiders, some can be found on top of rooftops and will attempt to shoot at the Sole Survivor from range. To gain access to the rooftop the Sole Survivor will need to walk up makeshift ramps towards a button to call a lift that can be used to access the rooftop where the MILA drop-off is. Once the MILA has been placed return to Tinker Tom for a reward and a new assignment.

Back Street Apparel
This location is defended by a group of Raiders and two turrets, one outside on the flatbed truck and the other inside on the ground floor. The Sole Survivor will need to enter the building to gain access to the rooftop where the MILA drop-off location is. Once the MILA has been placed return to Tinker Tom for a reward and a new assignment.

Mass Bay Medical Center
The medical center is defended by Gunners and a single Assaultron, there may also be a set of power armor inside the medical center which can be utilized by the Gunners. The Sole Survivor will need to enter the medical center and travel up two elevators to gain access to the rooftop where the MILA drop-off location is. Once the MILA has been placed return to Tinker Tom for a reward and a new assignment.

Four Leaf Fishpacking Plant
The plant is defended by a group of ghouls, there may also be a pack of super mutants in the building to the east if they notice the Sole Survivor. There is a staircase which can be seem to the right hand of the plant for easy access to the rooftop where the MILA can be placed at the northern most point of the roof. Once the MILA has been placed return to Tinker Tom for a reward and a new assignment.

The Boston Bugle
The entrance is through one small door on the side of the building. Take the elevator at the back of the first room you enter. After exiting the elevator you will see a door directly across from you. Take this to the roof of the Boston Bugle where you will find the area to place the MILA.
