There are numerous recorded cases of rape (according to various neutral NGOs present on the field), and there was that intercepted call of a Russian soldier getting permission from his wife to rape, as long as he used protection.

Saying the obvious fact Russian army rapes shouldn't amplify hatred, because the Russian army should already be hated and despised for it's brutality. To an extent it's not their direct fault because many of soldiers are just poor young guys acting on primal instincts with nobody to teach them better ( on the contrary, their war crimes are encouraged).
