Quite a few top-ranking people were involved in the preparations, such as the Ministers of the Interior, Justice and Defence, the Chief of Staff of the Defence Forces and the head of the political police.
Teadaolevalt olid ettevalmistustesse kaasatud vähemalt sise- ja kohtuminister, kaitseminister, kaitsevägede staabiülem ja Poliitilise politsei ülem.
