During the Independent Group's charge, the Federation's long-range firepower provided continuous support.
Through the perspective of the mechas, as well as military satellites, high-altitude unmanned reconnaissance drones, and ultra-long-range radars, any Imperial firepower platforms or combat units that appeared within the scope of detection or fired upon the Independent Group were precisely located by the Federation at the first opportunity, followed by merciless fire strikes.
The Empire's anti-missile weapon systems, due to the lack of air superiority, had a low interception success rate and had to rely on the advantages of cover to hold their ground.
In the Empire's view, the Federation's firepower was far inferior to its own, and after enduring the onslaught for a while and taking down the Independent Group, the Federation would suffer heavy losses due to this very rash battle.
