Look up Lenin’s Cheka, folks.
Things alike:
In Iran: “The Niruyeh Moghavemat Basij - the Mobilisation Resistance Force - was the strong right arm of Ayatollah Khomeini. Its volunteers were martyred in their tens of thousands in the Iran-Iraq war, and were given the role of moral police at home.”

In The Soviet Union: “The Cheka was created in December 1917, over a month after the October Revolution and the formation of the Bolshevik government. ... At the direction of Lenin, the Cheka performed mass arrests, imprisonments, and executions of “enemies of the people”. In this, the Cheka said that they targeted “class enemies” such as the bourgeoisie, and members of the clergy; the first organized mass repression began against the libertarian Socialists of Petrograd in April 1918. However, within a month the Cheka had extended its repression to all political opponents of the communist government, including anarchists and others on the left.”
