Replay the game. Altho you need to sacrifice Cass to see it, the entire weapons exchange is a trap. The NCR surrounds the warehouse and they kill the entire legion platoon.
I see. That is interesting.
yep. aniway gun runner and van graffs are against each other,and van graffs compete with their business rivals with assassination and unfair competition,against ncr laws. "the Van Graffs hate the
NCR mostly as they often stop their expansion with regulations and taxes. They also stated how at one point they would have been able to take on the NCR head-to-head, but as of the New Vegas era the NCR is said to be too large" (fallout wiki). What if Van graffs supports a revolution of some of the city-states in new california. New Reno,The Hub and LA. Many farmers could easely be against Shady Sands during the civil war due to the high taxes imposed by Kimball to sustain thr mojave militar campaign.
Also,some chapters of the brotherhod could join the war to subvert shady sands,fighting with Van Graffs even if they use energy weapons and open their bunkers to the wasteland while other chapters will remain loyal to the codex and neutral during the revolution.
