I am assuming there a lot of military veterans on here. I have a question about the term “201 File”

Bear with me, this question DOES pertain to Military History….. eventually…

I know it’s a term for someone’s personnel file, if you are IN the military.

But I am curious if that is an across the board term for employment / personnel file for ALL government employees? Would a civilian working on a military base have a “201 file”?

If someone who worked for the Federal Government but had never been in the military have a “201 file”?
Sure they’d have employee records but are they actually called “201 files?”

Would an elected Senator who was never in the service have something called a”201 file?” Not something “just like a 201 file” or something “just like a 201 file” but a file actually called “201?”

Why I ask is….

Assassin and former Marine Lee Harvey Oswald had a USMC “201 file”

But some books claim that former CIA agents said they saw a “201 File” on Lee Harvey Oswald.

That sure SOUNDS like Oswald used to be a CIA employee, doesnt it?

BUT, other books Ive read say that the CIA not only called their employee records “201 Files” but they also called the records of people they were snooping on / interested in “201 Files”

If thats true then by that same logic would the CIA have “201 Files” on people like Nikita Kruschev, Winston Churchill , Fidel Castro, Charles DeGaul, etc..

which is a little confusing to me. I would think the CIA would use a different word for their employees versus people they were keeping tabs on ( but what would I know?)

Is the phrase “201 file” an all purpose generic term used by the government for “information on people?”
