It’s not as strict as it was before but basically it’s a marker of your position. Those who are against it usually call it a war as well as, weirdly enough, the most radical supporters of it. Regular people between themselves often call it SMO (СВО in Cyrillic), not because they believe that it isn’t a war but because calling it “war” can still lead to a criminal case for the “discrediting of the Russian army”. To be fair I don’t think that they consciously choose to call it that every time, they’ve just got used to calling it that way now.Does Russia still call it Special Operation?
