The marked men base is a location in the Divide.
The area is comprised of a destroyed building with tons of debris and rubble around it. In front of the building there is a destroyed firetruck used as a watch for the marked men to watch for victims.
- There is a Camp Searchlight fire truck within the base.
- After blowing up the warhead, Blister will ambush the Courier with a small band of marked men (7-8 total). Their weapons depend on the Courier's level.
- Despite being called the "Base" there is no indication that this is where Marked Men coordinate with each other.
The marked men base appears only in the Fallout: New Vegas add-on Lonesome Road.
