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. Once you have reached the status of 'liked', you will be given the key to this safehouse by Lucius, leader of the Praetorian Guard. At this safe house there are multiple sets of legion faction armor and some weapons and 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 player can turn in a smaller number and complete a few Legion quests also, which may require less time than gathering 50 dog tags, depending on how much of the world the player has explored already and factors such as their stealth or weapon quality, etc. Another alternative can be to pick pocket the dog tags off of live NCR troopers, if the player is going to side with the NCR (rather than killing them) for no NCR fame loss and extremely minor Karma loss if not caught. Also, if the player has the NCR emergency radio, the player can call a NCR trooper and pick pocket the dog tag, wait 24 hours and repeat.
