Etymology and Origin of Moscow Rules

The original Moscow Rules come from Cold War espionage lore, credited to Western operatives who worked in Moscow during intense surveillance periods. They were practical maxims used by agents to avoid detection and capture. Over time, the phrase entered spycraft writing and popular culture as a neat label for field smarts.
