Tags of Our Fallen

Tags of Our Fallen is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
Quartermaster Mayes gives the Courier this unmarked quest after discussing the supply problems Camp Forlorn Hope is having. In order for NCR Command to better allocate supplies to their forces (including those at Forlorn Hope), they need to know what troops are dead. The easiest way to prove this for field troops is to bring back the NCR dogtag from each body. Therefore, Mayes is offering a reward for bringing those dogtags to him.

Reward
Mayes will give the Courier 2 bottle caps for every dogtag they turn in.

After turning in fifteen dogtags, the player character will receive a special reward from Mayes, consisting of 100 bottle caps and 6 beers, but one has the option to refuse the reward and earn good Karma.
