Factual error: In the beginning scene, Roadblock melts through the fence using some high tech gloves. The design and application of these gloves make no sense realistically. For one, the gloves are open fingered, thus causing great risk to Roadblock of even just a melted metal drip with a slight breeze. The intense heat, even if directed down towards the fence metal, would still be enough, if able to melt through metal in an instant, to burn his fingers as well, even from behind. It would be much safer, much easier, and much more practical to have the same type of device as an external stick or long object, or even an extension of a gun, keeping the hands out of harm's way.

Factual error: The sign outside Einsargen Prison says "high security area." For some inexplicable reason, the German writing just above reads "Hochsicherheitssteckdose", thus declaring the area to be a high security electric wall outlet. (00:25:40)
Factual error: They show the two people in suspended animation. Their vital signs are really screwed up. First the blood pressure shown is 72/75. The second number can never be higher than the first number as that would indicate backward blood flow. The pulse is shown in green is 22. The oxygen which is in blue is 45. The bumps only occur when the heart beats and would line up on the monitor to match the heart rate. (00:28:00)
Factual error: The shots of Fort Sumter in Charleston, SC show a bridge nearby. Fort Sumter is far out in the harbor - there are no bridges anywhere nearby. Fort Sumter is accessible only by boat, and there is no footbridge crossing a moat. (01:19:00)
Factual error: The warning sign at the gate of the Einsargen prison is hexagonal and says "HÄLT." The real word is "HALT" plus the real sign should be "STOPP", and it would be circular.
Factual error: When the French President uses his nuclear trigger, the device he uses has a button labelled 'bras'. Bras is the French for 'arm' as in arms and legs. Presumably someone was supposed to look up the word for 'arm' as in arm a weapon.
Factual error: You can't launch a tungsten (or any other heavy object) at a terrestrial target such as a city and create as much destruction as a nuclear weapon. The energy that creates the destruction is kinetic energy: Mass x Velocity^2. A Tungsten rod as depicted would need to travel at around ~400,000mph to create that destruction. That impact would also create an EMP disabling half the planet. (large/energetic asteroid impacts create EMPs and radioactivity too).
Chosen answer: Most likely Hawk was killed in action, or he just retired. Eventually Duke advanced to leader.
