Then we get to 4 and exactly 0 of any of it apparently mattered. Which would mean that in theory, anyone could use power armor, but not everyone can use it effectively if they are untrained. Mechanically it was required in 3 as well, but we do get a short explanation from the BOS there that you have to know how to work with the hydraulics rather than against them to use a power suit effectively.

up until 3 it was pretty much required to be trained to use power armor. I'd say it depends on how you look at it. All because your control of Power Armor is bad - after all, Power Armor has its own servos that increase power output of all your actions. For example, you can crush your weapon with your fist, move your legs the way it would topple Power Armor. The best example of it was probably shown in Macross Frontier where it was shown that the main problem of Power Armor is not your physical fitness but inability to precisely control Power Armor. You're a little wrong about Power Armor Training. It's like someone working a physical job learning to get used to the weight of steel toe boots and not trip everywhere like an idiot after years of wearing tennis shoes. Power armor training isn't like being a child learning how to tie your shoes. Try running around and shooting with your body encased in 200 pounds of pure metal, Protip: you can't, not without being TRAINED to use it effectively. Originally posted by naii_:armor of any kind isn't something just anybody can wear with no effort, especially armor as bulky as power armor.
