We have confirmed proof that Putin sent people originally assigned to those missile installations you mentioned to instead be cannon fodder in Ukraine. He is leaving plenty of places less protected (probably woth the exception of Moscow). Also, not all fighting skills are transferable. Some were not sent and probably wont be sent to Ukraine (except as cannon fodder) because there is nothing usefull they can do. If Russia still had unused human resources they would not be drafting at an enormous internal stability cost.
