on russian side it seems to be combination of conscripts that were ordered to march in and they afraid to disobey the order (while understanding that it's wrong thing to do) and of contract force that believes that ukranians are ruled by neo-nazi junta (with jewish president ?!?) and they come to free them. and those that don't want to be freed they are simply brainwashed. * based on a bunch of videos of captured solders and general communication between russian and ukranian sides on internet in last couple of days
