After reading the Politburo thread it seems the NKVD were acting beyond their authority in making changes to the actual file rather than making recommendations to the Marshal which can be disputed by the people in charge of those cities.
The Economic Minister was given control of many cities in the Caucuses region but it was not made explicitly clear whether that included troop movements/offensive operations if the cities came under threat.
2. Who is responsible for moving those units down in the oil field cities?
