Factual error: The Russians use a beeping "radio direction finder" to find the partisans by detecting a bug swallowed by the Mayor's son. In closeups the "direction finder" is seen to be an impedance meter (used for measuring AC resistance) - it's labeled "X=(down arrow) x (up arrow)(omega)". X is the standard abbreviation for impedance, omega means "ohms" (the unit of impedance/resistance), so the label says "impedance is lower dial times upper dial, in ohms". There is a piece of spiral twisted wire across the terminals of the impedance meter which would be useless for radio direction finding. (01:19:15)
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.
Factual error: When the Soviet airborne troops first drop into Calumet in the first few scenes of the movie they are using US Army issue parachutes - MC1-1B. (00:04:45)
