I've been replaying Fallout and I noticed that the Legion does not have very many tents on the other side of the Arizona river at the Fort. We also know no other Legion troops west of the Colorado are going to be taking down the other camps and the bridge would not be standing. Also given the weapons adjustment in which the NCR's AR-15's act like AR-15's and the presence of NCR Heavy Troopers with Incinerators, Heavy machine guns, and rarely Missile Launchers vs Legionaries half of whom ONLY have machetes...can someone explain to me the idea that the Legion has enough troops present at the Hoover Dam to dislodge the NCR? Where in game do we see the Legion has enough troops to get the job done?
