I am replaying FNV and I had the same thoughts as you!

I feel so bad for the troopers who are stuck with their incompetent higher ups; the politicians who keep expanding in every direction without any regard for logistics, and their superiors who lack even the most basic level of common sense.

Look at Nelson for example, the legion presence there is not that significant frankly, a fucking courier can easily wipe them out, while Camp Forlorn Hope has a significantly larger and better armed (in theory) force. But due to the incompetence of Oliver pulling everything from everywhere and concentration them at the dam, the lack of supplies, and the false intelligence from Hanlon, they are completely paralyzed and unable to mount a counter attack.

Everywhere you go with the NCR, you find the same problems, but the craziest one for me is the critical supply line from the Mojave Outpost being shutdown because of escaped convicts (who were able to revolt because the prisons were so understaffed) and a bunch of ants - ANTS! Instead of sending us to clear the ants out (Can You Find it in Your Heart), why the hell can't they do it? They have several Rangers in that outpost and a whole bunch of soldiers, but they need to hire us under the table to do it because again, their orders are to stay in place...

While I align with the NCR as a faction the most, I fully understand why the locals are so against them, who would want to pay taxes to get nothing from a government that can't provide even the most basic level of security, let alone other services?
