Andy and Charlie

Andy and Charlie is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
Former NCR Ranger Andy will ask the Courier to check on Ranger station Charlie. Upon arrival, it becomes apparent that all the rangers have been killed by legionaries, who left behind two holotapes. The first is located under the desk, and the second one is on top of a metal box next to the desk.

The first holotape is an abortive log recording by an unsuspecting ranger just before the attack. The second holotape is a recording of a legionary boasting that by wiping out the base, they are sending a message to the NCR. The legionary also states that they took a female Ranger captive - the same female Ranger that can be fought in the arena at The Fort.

Returning to Andy with the news will net 200 caps, plus reputation with both the NCR and Novac; more Novac reputation gain than NCR. Passing a speech check (60 Speech) will net less reputation with Novac but an additional 200 caps and more NCR reputation.

After this unmarked quest is complete, Andy will offer to teach a special unarmed move, Ranger Takedown. He will also offer to train this move without completion of the quest upon the passing of a (30) Speech check.

Bugs

 * Even if this quest is not active, people may sometimes say, "I heard there was a massacre at one of the ranger stations, not sure which one though." although nothing yet happened there.
 * It is possible to learn the Ranger Takedown move twice by completing this quest and by passing the Speech check.
 * After speaking with Andy and traveling to Ranger station Charlie, you may find no rangers outside, but once inside the station the only living person will be Comm Officer Stepinac, causing no holotapes to spawn and rendering the quest impossible to complete. This happens when you start the Return to Sender Quest after this one, since this quest requires you to deliver the new codes to Stepinac.
 * Sometimes while listening to holotape 2 and stopping the recording before it finishes or vice versa with holotape 1 can cause the quest to be impossible to complete, when asked what you found at the station you will not have the option to inform Andy that the ranger base was attacked by the legion, but simply say you found bodies but no evidence as to who killed them thus no completion of the quest.
