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 Russians don't get rid of anything. Its said if you want a World War I Mosin-Nagant, you can still buy one from one of their warehouses. While no one can prove if this is true or not thanks to the fact that we're currently in full retreat, its likely true. This is another case of them hanging onto old materials. Using the V3 Chassis developed during the first great war, and a new high-speed missile, they've developed this brand new system. The vehicle moves significantly faster than its predecessor, and with significantly better fuel economy. Add to this the high speed and nearly un-hittable missile it fires, and this is one of the UAN's more deadly artillery pieces.
