The weapons carried by the Scott and Stonebridge and the Georgian forces during the bunker assault look like AK47s, but are in fact Czechoslovakian SA vz.58 assault rifles (probably because the scene were shot in the Czech republic). The SA vz.58 is rarely found within the former Soviet republics. Georgian special forces would rather rely on the M4 or AK74 rifles.
Despite knowing the target has access to nerve agents no-one on the assault team is equipped with protective gear or detection equipment.
The damage projection is complete nonsense. There is no instant-death zone and none of the listed symptoms for the other zones are accurate, most notably burning.
Scott looks at a device in the lab and declares it's "a vx". Firstly VX is an agent not a delivery system, secondly it can't be visually identified and thirdly the liquid in the device is blue while VX is amber.
When Major Sinclair requests a landing zone to rescue Stonebridge and Scott, he pronounces it ell-zee. The British pronunciation for the letter Z is zed.
