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.
Factual error: In the opening scene of the movie, the Soviet paratroopers are seen wearing smooth, black, leather parachute helmets. But Soviet Paratroopers have always worn tan, cloth parachute helmets with ridges that resembled tanker helmets. (00:05:00)
Suggested correction: Actually no, The Soviet airborne would have had leather helmets when they jumped in circa 1984.
Continuity mistake: After the helicopter attack where Toni and Robert are killed, the Russian helicopters land about forty feet apart, the officers get out and walk to meet each other at the halfway point. For the rest of the scene, they are right next to one of the helicopters. (01:38:30)
