Tour of Duty

Tour of Duty is a Brotherhood of Steel main quest in Fallout 4.

Detailed walkthrough
In order to become an effective part of the Brotherhood, Elder Maxson has ordered the Sole Survivor to tour the Prydwen and get to know her crew. There is no strict order in which one has to meet each individual. One can find Proctor Ingram near the power armor station (the set of power armor can be found in Bay 3) and with a medium speech check the player character can ask her about her missing legs, which opens up opportunities to further the conversation.

Locate Proctor Teagan at the supply store. Aside from the impressive array of weapons he sells the Sole Survivor can ask him about extra work opening up the radiant quest Feeding the Troops. Locate Proctor Quinlan at his office. Speak with him and one has the option to locate some paper for him, opening up the radiant quests Getting Technical and Learning Curve. Locate Knight-Captain Cade in the sickbay. Speak to him and complete a medical check-up. The Sole Survivor is able to return to him whenever in need of medical assistance.

Bugs

 * In some of cases Elder Maxon could freeze after ending of this quest and never take you to the next. There is no solution to this problem now except maybe console commands.
 * If any of the characters in this quest die indirectly the quest won't fail and it's impossible to end. This leaves many of the brotherhood side quests frozen.
