We don't really even know if that wave was russians, they could have all been confused people fooled into frontline military service from different countries, russia probably doesn't even know which doesn't mean they shouldn't be stopped with force but also recognize russia is BEGGING you to dehumanize and flatten these people so they can convince gullible foot soldiers being sent to die for absolutely senseless reasons into thinking the other side are the real enemies instead of the russian state.
The russians you are imagining absolutely exist, obviously, but also question the simple narrative that this can be reduced to that.
