GOOF: In the 31 minute mark, when Jack grabs the assault rifle from the fallen Chinese soldier, there's one second when you can see that the magazine is off, and the next there's a magazine on, and the next second again there's no magazine, and the next there is one.
Cheng tells his team that CTU is only 153 metres from their position, however it takes the team about 15 minutes to go that short distance.
Doyle: And there's something else. We found a whole bunch of empty weapon crates.
Nadia: What kind of weapons?
Doyle: Large calibre rifles, military-grade C4, grenades. Enough of an arsenal for a small army. Looks like the Chinese are planning to launch a major assault.
Nadia: Assault on what?
Zhou: We're at the junction point.
Cheng: Good. Head East 153 meters. That will put you directly beneath CTU and the entrance point.
