How Are Operation Code Names Chosen?

Code names are assigned to hide an operation's true purpose and scale from the enemy, and are often drawn from random word lists or mythological names. But when an operation becomes significant enough β€” through success or failure β€” its code name itself becomes a lasting proper noun tied to that event in history.
