Закавказский фронт
The Royal Navy and Royal Australian Navy attacked from the Persian Gulf while other British Commonwealth forces came by land and air from Iraq. The Soviet Union invaded from the north, mostly from Transcaucasia, with the 44th, 47th armies of the Transcaucasian Front (General Dmitry Timofeyevich Kozlov), and 53rd army of the Central Asian Military District, occupying Iran's northern provinces. Air force and naval units also participated in the battle. The Soviets used about 1,000 T-26 tanks for their combat operations.
