I have one. FO3 Enclave: with all there power, advanced weapons, robots, vertibirds and numbers, why did they not just take DC and the area around it? I am sure they could have. Final quest they have outposts all over and tthose force fields they have. Why did they wait for the Wanderer to come along and hope he/she would help? Without him/her their plans would be useless.
Another question where did they get all that power, weapons and men from?
Because they were Bethesda's Enclave, A.k.a. AI's arn't the best military commanders.
Question 2: In Fallout 2's enclave, They made their own Advanced Power Armor MKII by modifying the regular T-51B Power Armor, So they probably just used stored weapons/armor and the men? They have a military base, So they probably live there and repopulate...
Also to the question about Victor...
He did'nt, He gets killed along the way to Vegas, If you see him die you can ask him about it later, But he controls different Securitrons, So the one closest to where he died he started controlling so that kind of explains that.
