The year is 2055, more than thirty years after the events of Zero Hour, Earth suffers a catastrophic collision with meteorites. The world is thrown into turmoil as large swathes of land are annihilated. Four factions, the ADF (Asian Democratic Federation), WEA (West European Alliance), WLF (World Liberation Front), and AC (American Confederacy) are at war for control of the remaining already harder to find resources as well as the preservation of their nations and geopolitical interests. Welcome to Deep Impact.
The AC struck a deal with the Patriot Supplies weapons manufacturer to create a combination of a powerful flak tank and an agile transport unit capable of carrying infantry to many places on the battlefield. The dual burst guns make sure no aerial units get within their range by blasting bursts of flak towards their targets, shredding them in seconds.
A recommended tactic for aspiring commanders it to load the Sky Knight with two Hawkeye troopers and un-garrison them to help engage both ground and air based threats. To help its accuracy, it has 2 laser targeting beacons mounted on top of the guns to help guide its normally inaccurate flak guns.
