A Trusted Aide

A Trusted Aide is an unmarked quest in Fallout: New Vegas.

Quick walkthrough

 * Work for Caesar's Legion in order to gain access to Caesar's Legion safehouse.

Detailed walkthrough
Continue doing assignments given by Caesar's Legion members and earn their respect. Reaching the status of 'liked' yields the key to this safehouse from Lucius, leader of the Praetorian Guard. At this safe house, there are multiple sets of legion faction armor and some weapons. The safehouse is made of two rooms connected by stairs.

Reaching a "liked" reputation can be accomplished multiple ways; one of the easiest may be to turn in 50 NCR dogtags to Severus or Aurelius of Phoenix. The Courier can also turn in a smaller number and complete a few Legion quests, which may require less time than gathering 50 dog tags. Another alternative, if the Courier is going to side with the NCR, is to pick pocket the dog tags off of live NCR troopers, since this causes no NCR fame loss and only minor Karma loss if it is done while remaining undetected. Also, having the NCR emergency radio makes it possible to call an NCR trooper, pick pocket the dog tag, wait 24 hours, and repeat.
