I'm sure that Facebook will be checking the persons targeted on their platform for registration in the Russian army but do you suggest that you are alright for Facebook to facilitate the the mentioned actions as long as they restrict it to soldiers?

I can't speak about the first part (I assume posts of this nature aren't really going to mention individual soldiers by name), but yes I do think it's okay for Facebook to facilitate violence when it is a clear case of self defense. I think organized guerilla warfare against a powerful invading army is a perfect use case for a neighborhood social network.

They didn't answer. This is a really tough one for them I see
