Detailed walkthrough
Former NCR Ranger Andy, will ask the courier to check on Ranger Station Charlie. Upon arrival at Ranger Station Charlie, you will find 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 a metal crate 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. Passing a speech check (60 Speech will net less reputation with NCR and Novac but 200 additional caps.

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