Mayes request is a paper note in Fallout: New Vegas.
It is added to the player character's inventory after Quartermaster Mayes asks them to retrieve any dogtags found on dead NCR troopers. This starts the unmarked quest Tags of Our Fallen.
The NCR at Camp Forlorn Hope are short on supplies. Quartermaster Mayes is looking for Holotags to track fallen soldiers and reallocate inventory. Your assistance will be appreciated.
