Russian invasion of Ukraine

Pershaps not the most easily verifiable story, but some genius has organised the Russian army along ethnic lines and according to this article cracks are starting to show:

One of the reasons for this ethnic conflict is the reluctance of the Buryat soldiers to conduct offensive operations and their perception of the "inequality" of their circumstances compared to those of the Chechen soldiers. The latter are never on the frontline – they always remain in the rear as "barricading detachments." Their task is to ensure the units of [Russian] occupying forces maintain active military action. That is, to open fire on those [Russian troops] who are trying to retreat."
