This lengthy silent film (which likely was intended to be narrated by whoever presented it) was prepared by the Persian Gulf Command for Allied and Soviet leadership (and features both Russian and English intertities). It shows the PGC's activities in Iran during the Second World War. If you take a good look at this film, you'll get an idea of how vast the Allied supply effort to the Soviets really was — as literally hundreds of millions of dollars of aircraft, tanks, and various supplies are shown being offloaded in Iran and hastily shipped north to the Eastern front.
