it was controlled by natives and dogs yes, but the NCR could also defend their cities
evacuate the population, leave behind a contingent of troops with enough supplies for them but not enough for the Legion
the NCR has a lot of weaknesses in how they approach warfare, but their strengths are particularly well suited at urban warfare, they have plenty of automatic rifles and bullets to feed them, easy access to explosives, their rangers are very well trained for small unit tactics and asymmetric warfare
it would be ridiculously easy for the NCR to force the Legion to take a city block by block, losing immense amounts of soldiers in the process failing to find the relatively low number of defenders since the Legion just isn't set up for that kind of warfare
And again, these are not hypotheticals, Boulder city shows what rangers can do to the Legion, the Boomer's bomber ending has the Legion refuse to even try to annex them because the casualties would be so horrendously onesided, the Remnants ending has them successfully engage in a guerilla campaign against Lanius, despite being outnumbers like 5000 to 1 and most of them being 80 years old
And after all this shitshow, after spending weeks clearing out a city block by block, there's no god damn food anywhere and they have to march several weeks to reach the next city
The legion flat out cannot do that
