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.
