  Nikolai Efimovich Varfolomeev (Russian: Николай Ефимович Варфоломеев; 29 September 1890 – 8 May 1939) was a Soviet military commander and theoretician. He and Vladimir Triandafillov made significant contributions to the use of technology in deep offensive operations. Varfolomeev was one of the foremost military theorists teaching at the RKKA Military Academy. He was executed in 1939 during the Great Purge.
  
  ## Deep operation
  
  Varfolomeev, unlike Triandafilov, was less concerned with developing the quantitative indices of deep battle, but rather the mechanics of the shock army's mission. Varfolomeev termed this as "launching an uninterrupted, deep and shattering blow" along the main axis of advance. Varfolomeev believed the shock army needed both firepower and mobility to destroy both enemy tactical defences, operational reserves and seize geographical targets or positions in harmony with other operationally independent, but strategically collaborative, offensives.
