In my headcannon they're kinda like the IDF, good at killing civilians with a horde of melee wielding psychopaths and storming the settlements of helpless tribes, but the minute they encounter an actual military force, out goes the ideology and in comes the firearms and presumably the hoard of weaponry collected from 87 tribes would be substantial enough to give the failing NCR a headache
Plus the Colordo river and Lake Mead are extremely defensible locations, even a horde of dipshits fascists could hold it for a while
