In the Battle between Gods and Heroes, ordinary soldiers didn't even qualify as cannon fodder.
No amount of attacks from mechs or even warships for that matter could possibly make a difference against those who wielded Saint Kingdoms and even stronger domain fields.
The very space around the powerful entities turned into impassable regions. Nothing could get past these powerful fields so long as their sources did not allow for it. Just this defensive measure alone was enough to make many mortals give up their futile thoughts of defeating their opposing gods!
Even expert pilots such as Venerable Dorsa Avinx found herself unqualified to join the ranks of the heroes that fought at this crucial level.
She had only tried to attack the Cold One once with her submachine gun before she personally felt how the dark god easily crushed her resonance-empowered attacks without conscious effort!
