Who did Stalin purge from the Soviet communist party and the military?

The Great Purge from 1934 to 1940 was used to effectively remove dissenters of the Communist Party from leadership, government office, and the military. Several millions of people were detained with an average of 1,000 being executed a day during the most violent years.

These acts of terror and the goal of total power by Stalin is one of many reasons that Stalin's body was removed from the tomb with Lenin in Moscow.
