Revealing mistake: If a player has a rocket launcher on their back as a secondary weapon, sometimes after getting killed, the death animation has the character throwing his head back. The back of the long rocket launcher tube goes into his head.

Factual error: 2011 Model Jeeps weren't around in the 1960's.
Factual error: The CZ 75, ASP 9, MAC-11, MP5K Prototype, Spectre M4, PM-63 RAK, OTs-02 Kiparis, FAMAS F1 FELIN, AKS-74U, IMI Galil ARM, Steyr AUG, G11K2, Enfield XL64, SPAS-12, KS-23, L96A1, WA 2000, PSG-1, SA-14 Gremlin, M202 FLASH, BGM-71 TOW missile, AGS-30, M203,GP-30, Masterkey, and GSN-19 Kanarejka were not around in the game's time frame.
Factual error: During the cutscene on the Russian freighter while Steiner explains Dragovich's sleeper cells, a soldier is firing off rapid photos with flash. The camera resembles a 1960s 35mm rangefinder, which would have required manual film advance and single-use flashbulbs or a slow capacitor recharge. Such cameras of the era were incapable of continuous, strobe-like flash photography, making this depiction inaccurate.
Audio problem: In the 1945 flashback, when Reznov is talking at the start, saying "Yes, Dimitri... Time to hunt down the last remnants of the fascist Reich," his head is bobbing up and down as he speaks, but his mouth is not moving.
