>>5451897>we can disable their movement using our near-infinite numbers of auxiliaIt's probably this bit right here that might pose the issue.
In any battle the 2nd Legion strives to achieve superiority of materiel, personnel and machinery. Vast numbers of Skitarii, Cybernetica, Servitors and this isn't even considering we have yet to enact the Tech Thrall legions too, plus not only more armored and air support but superior patterns of tanks. One to one our tanks are meant to be superior to the equivalents of our brothers, with more awoken machine spirits, expert crews, and eventually superior armor and weapons system. And we do not intend to remain on one to one tank numbers.
Eventually anyway.
So if we win using our traditional methods, Fulgrim would just claim we are cheating.
In any case at this early in the war, he probably can't even muster a fraction of marines to match our marines alone, let alone to match our hordes of auxilia.
