Detailed walkthrough

 * Speak with Tech Sergeant Reyes at the Camp Forlorn Hope Command Tent to gain this quest.
 * Deliver the radio security upgrade codes by speaking to the communications officer at each of the ranger stations.
 * Upgrade Ranger Station Alpha
 * Upgrade Ranger Station Bravo
 * Upgrade Ranger Station Charlie (if Ranger Station Charlie has already been wiped out, you don't have to visit it, even though it is still stated as a quest objective)
 * 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. (Note: it is possible to skip the double-check, by pick-pocketing the reports from the Rangers you are supposed to speak to; they are in their respective inventories. If you have them, walk out of the tent and then back in and speak to Reyes) 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 with his revolver. He drops his Ranger Sequoia revolver which can be stolen and you'll gain 500 XP.
 * If you let Hanlon continue his plan without informing the NCR, he walks off and you get 550XP.
 * If you have killed Caesar, you can convince Hanlon to come back to his senses and cease falsifying the reports, and you get 500XP.

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 semi-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 or run in and grab it before the Ranger runs in to investigate the gun shot. Alternatively, nudge the intruding Ranger out of the room and close the door before grabbing the weapon.''

Behind the scenes

 * "Return to Sender" is a 1962 rock and roll hit single by American singer Elvis Presley. The song was written by Winfield Scott and Otis Blackwell. It is about a man mailing a letter to his girlfriend after an argument.
 * If the Courier goes to Hanlon at night, he finds Hanlon going from bed to bed with various NCR soldiers.

Bugs

 * Sometimes you can turn the first part of the quest in without bringing the new codes to Ranger Station Foxtrot.
 * 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. Walking into him as if your trying to push him MAY work as it worked for me in this situation, but if not... 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. I was able to fix this glitch by telling my companion to return to lucky 38 and before he could leave I recruited him to follow me again. Right after that Hanlon walked upstairs to the balcony.
 * Sometimes he will get stuck in a mass crowd of other NCR members. A way to fix this is to use a silenced weapon (or melee) to 'sneak kill' all of the NCR soldiers that are in Hanlon's general vicinity. Almost immediately after this he will begin to move once more.
 * If you stole his Ranger Seqouia already, he will drop a second Ranger Seqouia on his suicide.
 * Even after Chief Hanlon commits suicide, the NCR Ranger that runs in to guard his body will say, "you should talk to Chief Hanlon if you have any questions. He's usually on the balcony" if you talk to him.


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