Long long ago, quite a number of mages deeply held that it was of no use for mages to learn military knowledge.
But more often than not, the cases of the mage dispatch being detected and suffering from a sneak attack by the enemies had become a common scene in the war in both the Demon and Zence Empire.
Mage troops without strong commanding capabilities would nine out of ten times end up being wiped out on the whole in case of a sudden and deadly sneak attack.
While those mage troops possessing excellent commanding proficiencies could deploy a wise and poised command at such perilous moments, to fend off the enemies' attack until the rescue dispatch came or directly beat them down.
Drawing lessons from these totally different outcomes of the war with or without commanding provisions, no mage would say that military knowledge was of no use to them.
