Continuity mistake: In the level Second Sun, when you take control of Ramirez for the second time, the EMP doesn't hit until a few seconds pass. You can tell because the street lights and helicopters are still fully functioning. However, your holographic sight has already been disabled.
Factual error: When the M16A4 is mounted with optics the front sight as well as gas block are removed. Without the gas block the M16A4 could only fire one shot before having to be manually actuated.
Factual error: The M4A1 is not depicted with an ejection port or a forward assist.
