Input: Question: What did "Four-F." mean in the United States of the 1940s? Here is the quote from Catch-22: They had to send a guy from the draft board around to look me over. I was Four-F. I had examined myself pretty thoroughly and discovered that I was unfit for military service 
Answer: It's a classification for military service. 4-F means "Registrant not acceptable for military service.". The context clue here you might have used to deduce an area of inquiry would be the reference to a "draft board", which is part of the Selective Service System that determines the eligibility and thus the classification of potential draftees.
