User blog comment:Gundam Legilis/Faunus... inferior or superior?/@comment-23790511-20140419161451/@comment-11188061-20140419165503

The ability to see clearly 24 hours a day meant that they or example, could easily set up a daily night ambush against the Humans, and that means that invading the Faunus will always be disadvantageous for Human troops. Moreover, since Blake is a Faunus that also meant that Faunus have Aura and Semblance just like Humans do and just as smart, so physically speaking the Faunus are superior over the Humans at almost every way.

That's why the Humans are developing droid technologies. The security droids will replace Humans in combat (we already are doing so in real life; limiting the number of Human lives lost by using long ranged weapons, spy droids etc) and they are technically infinite in numbers.
