It was fairly well known that the Russians started with 190,000 troops allocated for the invasion. If you add the upper limits together for the KIA and the Wounded for Russia, that adds up to roughly 190,000
What troops they have in theatre now is impossible to tell but they have lost a huge chunk of that initial, fully trained and partially battle experienced cohort but you still have to imagine they have in the region of 150,000 troops on the ground, its just than now, they really aren't very good
