They did yeah. There was this whole hashtag-like thing on Telegram where people who had a regime uniform in their wardrobe would stuff it in the trash. It was mostly demobilised conscripts, policemen, and such. There was also one high ranking retired officer who openly spoke out against the regime, who’s in exile now.
Having written that, so yes and no. As in, I don’t think there were many (any?) active service members. That likely would’ve been very dangerous. But people who had close and recent ties with the military, so could be expected to be regime loyalists, yes, plenty.
EDIT: I never follow Ukraine, Russia, or Belarus on “Western media”. I read Russian, so I follow a bunch of Telegram channels from those countries. The protests in Belarus were basically covered live.
