Yes I feel sorry for these guys too. They aren't signing up to fight for money. They have been conscripted, most likely against their will, without proper training and probably without decent weapons, to fight a very motivated, battle hardened and better supplied army.
This could play to Russian strategy- when you throw these guys into battle with no shelter, no food and no winter clothes, what do you think they will do? They will commit war crimes against civilians which is what Russian probably wants
