Recruitment Blues

Recruitment Blues is a main quest and achievement/trophy in Fallout 76.

Background
Fort Defiance was found by the dwellers, but its secrets - and especially the knowledge secreted away on the top floor, behind top grade military security - are not yet ripe for the picking. The dwellers need to gain a military ID in order be recognized as worthy of entrance.

Quick walkthrough

 * Take the elevator to the top floor of Fort Defiance.
 * Register for elevator security.
 * Search for clues to bypass security.
 * Complete Back to Basic.
 * Obtain a military ID card by completing a series of bureaucratic steps involving collecting forms and talking to robot clerks at the Charleston DMV.
 * Register for the Brotherhood of Steel.
 * Investigate the Brotherhood and Scorchbeasts.

Detailed walkthrough

 * Take the elevator to the top floor.
 * In "Fort Defiance," take a right at the locked door and head through the opening ahead. After taking another right, you will find an elevator with a laser grid blocking your path. To pass, you'll need to register yourself on the fort's security system.
 * Register for elevator security.
 * Head back to the bulletin board and follow the hall and up the first ramp. Continue to the second and third floors until you reach another elevator with a laser grid block.
 * Use the terminal and select "Register new personnel."
 * Note: The terminal will say "Access denied." This is working as intended.
 * Search for clues to bypass security
 * Head to the room at the other end of the hall where you'll find a note among the shelves near the middle of the room labeled "Squire Evelyn's Journal-- Page 16."
 * You need a military-issue ID, which you can obtain by completing basic training at Camp McClintock. If you’ve done that already, you must have your ID printed.
 * Note: The "military-issue ID" is the Soldier's Certificate you receive as a reward for completing Back to Basic. Make sure it is in your inventory.
 * To have your ID printed, you will need to head to the DMV.
 * If you have not completed "Back to Basic" you will need to do this now.
 * Survive the DMV
 * Obtain a military-issue ID and head to the Charleston Capitol DMV near the Charleston Capitol Building.

 * Approach DMV bot B2 and print a number from the printer to the robot's right.
 * Head to the computer terminal in the center of the room and select "Boot up Department B."
 * Fight off waves of Feral Ghouls as you wait for your number to be called.
 * Once your number is called, speak with DMV bot B2. He'll ask you to retrieve a piece of mail.
 * Leave the building to find an old mailbox on the ground. Loot the Junk Mail from it and head back to the DMV.
 * Back at the DMV, talk to DMV bot B2. He will ask you to retrieve another form.
 * Leave the DMV to visit the Charleston Capitol Courthouse. Head to the bottom floor to find the "Blank DMV-AT-21C-V form." Head back to the DMV and hand it over to DMV bot B2.

 * Once DMV bot C1 finishes his coffee break, he will ask you to provide a valid birth certificate.
 * Use the terminal to learn about "Error 34B/1" and figure out why your birth certificate isn't valid.
 * Find the "Governor's Seal" in the room to the south. Use it to stamp your document.

 * Register for the Brotherhood of Steel
 * Travel back to Fort Defiance and head to the terminal at the top of the building.
