So basically a demoralized, under-equipped, under-trained army fighting far from home that represents a tiny fraction of the NCR's military might guarding a tiny amount of land while led by an idiot (Oliver) is still managing to hold the line against everything the Legion can afford to bring to bear.
Doesn't speak too highly for the Legion's effectiveness.
Okay?
Searchlight, gone.
Nelson, gone.
Nipton, gone.
Ranger Station Charlie, gone.
Cottonwood cove, legionized.
I don't remember if he was behind Graham's failure but that was the only time that NCR was able to hold back legions forces.
And this time, Legion's forces are in greater quantity than Grahams unit was.
And Legion could always try to take over the northern part of Lake Mead by going there with rafts and then corner the dam from 4 sides. (North, south and west by Legion and west by Khans)
Don't really see how effective Oliver is at holding the line. :shrug:
