Yep, that was my mindset on Power Armor as well in FO1, only the BOS had working suits. The whole "power armor" training was inserted in from Fallout 3 to prevent the player from using it at the first third of the game when he would come across suits in GNR. In a way it makes sense to a degree that someone needs to be trained to use Power Armor but if everyone else outside the player can use Power Armor immediately once they are equipped with it I think it is more giving the player the middle finger because they can't until the game allows it. I know that NCR power armor had its servos removed so that it could be used by non trained personnel, at least that is the lore explanation. Still I think that in at least in West Coast and nearby places the NCR should eventually be the Power Armor using faction, fully working Power Armor armor. The BOS simply are played out as a faction in general. I don't hate them but the games I consider canon have made it clear that they are a faction in decline because of their own failing ideology and politics. Bethesda ignored all of that when they made Fallout 3 because they wanted to make the BOS the "cool" Power Armor wearing faction.
