Return to Sender

 is a quest in Fallout: New Vegas.

Detailed walkthrough

 * Speak with Sergeant Reyes at the Camp Forlorn Hope Command Tent to gain this quest.
 * Deliver the radio security upgrade codes to each of the ranger stations.
 * Upgrade Ranger Station Alpha.
 * Upgrade Ranger Station Bravo.
 * Upgrade Ranger Station Charlie. (Possible Bug, see Bugs Section below)
 * Upgrade Ranger Station Delta.
 * Upgrade Ranger Station Echo.
 * Upgrade Ranger Station Foxtrot.

After you're finished you're sent back out to several stations to double-check the intel reports. Then you must go to Camp Golf and confront Chief Hanlon about it. He can be found on the balcony above the entrance to House Resort during the day.
 * If you decide to turn him in, he commits suicide after you leave the room and you get 500XP after returning to Reyes.
 * If you let Hanlon continue his plan without informing the NCR, he walks off and you get 500XP.
 * If you have killed Caesar, there is another dialog but it ends up about the same as keeping it a secret.

Your choice to turn in Hanlon or not doesn't affect the situation at the dam.

''Note: If Hanlon kills himself he drops his Ranger Sequoia revolver, a rather unique weapon that uses the .45-70 Gov't ammo. The weapon is in perfect condition. To obtain the weapon drag it to an unoccupied room.''

Behind the scenes
The name is a reference to the Elvis Presley song of the same name.

Bugs

 * Sometimes you can turn the first part of the quest in without bringing the new codes to Ranger Station Foxtrot.


 * If you already did the unmarked quest for Ranger Station Charlie it won't appear as one of the targets, though the dialogue option still exists to inform Reyes that Charlie has been wiped out. The quest can then be completed normally. (confirmed on PC and Xbox).


 * It is possible for Hanlon to become glitched so that he remains stationary and never goes out to the balcony. He will not enter dialogue with the character and the quest cannot be completed.  Sleeping, waiting and fast traveling are all unable to fix his lack of movement. Loading a save prior to entering the building can fix this. Also, you can, after realizing he is glitched, exit the building, then wait out in front (real-time waiting) until he comes out on the porch, then re-enter the building and proceed to the porch (PS3).


 * Chief Hanlon may remain stationary in mid-air after his suicide.


 * After talking with Hanlon on the balcony he tells you to come to his bedroom to continue the discussion, but when you arrive in his room he's not there, even if the cursor indicates his bedroom. Sleeping, fast traveling, time shifting and real-time waiting (searching him by day and by night) doesn't fix the problem. Funny that in his bedroom all the pictures are about magicians and illusionist, in fact not so funny as you can't finish the quest. (Xbox) [Try checking his office, downstairs, off the hallway directly across from the entrance double doors]
