Yes, the Tsars were de facto heads of the Orthodox church, and the Metropolitans all toed the government line. Even under the Communists, the church maintained it’s subservient role. Stalin used the church to his advantage during the Great Patriotic War, even giving a joint radio address with the Metropolitan.

In return the church took up a special offering and “purchased” a brigade of T-34’s for the state.

Not subservient role at all.
Stallin had to negotiate with Church.
As for role of Church, one of basic teachings of Orthodoxy is selfsacrafice up to the point of suicidal courage in order to protect Christian vales or state.

Per example, when Orthodox child is born, it will be thought to respect church, be a good Christian and be ready to sacrifice in order to protect word of our Lord, and country.

For all Orthodox, Church=God=Country
When country calls you to go to war, it is like God called you. We are thought our entire lives that it is ultimate honor to give your life to God and Country.

That may explain how Serbs, Greeks and Russians fought so stubbornly In wars.
