The heaviest losses compared to the population so far were being suffered by the mostly Buddhist Mongol groups (and a former president of Mongolia just appealed for the Russian Mongols to seek asylum in Mongolia).

But Dagestan was also hit hard, while figures from Chechnya are just unavailable.

By sheer numbers it's the conscripts from the occupied territories, being mass mobilized since mid February and often given WWII weapons and gear.

Barely anyone from Moscow besides career officers and some police/FSB types.
