For Ozpin to have fought in a war 80 years ago would mean that either human lifespan is much longer in Remnant, or that Remnant's years are shorter than Earth's, by a substantial amount, given that he looks like he's in his fifties/sixties at most. However, we've yet to see the Faunus War's dates mentioned. It could been fought earlier than the Great War, during the Great War as a conflict within a conflict, or later. I prefer the last option, as it would make sense for the Faunus War to have occured in the last 60-40 years. See, so far, we've seen nothing of anyone who had been alive and affected by the Faunus War, with lost friends, family, etc. This means that most of those people have probably aged out of public life, etc. That's also enough time for the White Fang to have gone through a second generation of members who had been brought up with the original member's values and followed them, and start the rise of militant radicals who were frustrated with the lack of progress for Faunus Rights and were ignorant of the horrors of war because they hadn't experienced one in their time yet, eventually building up to their take-over of the WF. Compared to the small timescales young people usually think in, the Faunus War would also classify as "ancient history" to the students of Beacon as Oobleck puts it. Though I admit that Oobleck could've been talking a much bigger timescale, being that he's a historian. Thus, I think the Faunus War is perhaps the most likely one that Ozpin would have fought, unless other major conflict, such as a rebellion, had occured that we haven't heard about yet.
