Factual error: When the Russian tank rolls up to the two gas pumps, the crew have a choice of regular gasoline (as indicated on the pump), or Good Gulf (a premium gasoline). And in fact one of the tankers tells the attendant, "Gasoline." The trouble is, all Soviet tanks, from the T-34 up through the T-80, have diesel engines for safety reasons. (00:46:55)

Suggested correction: Most variants of the T-80 use a Gas Turbine engine, which can use basically any flammable liquid.
The tanks in the movie were mocked up to be T72s, which were diesel.
