“So Rybar suggests there will be a reshuffle in the MoD, but instead of Shoigu and Gerasimov, it will be Rudskoy (Main Operational Directorate), Buvatlsev (Main Combat Training Directorate), and Burdinskiy (Main Organizational Mobilizational Directorate).”

Well, while Wagner was Russia's biggest and most well know PMC, Prig wasn't the only guy with such a private army. Shoigu has his own PMC, "PMC Patriot". Shoigu also has a new offshoot called PMC Storm-Z, made up of convicts that he formed by cutting off Wagner's access to prisoners and taking them himself. PMC Patriot and Storm-Z are positioned in the south. Sacking Shoigu could have repercussions there if not done with tact and consideration.
If Putin gets rid of ALL PMC's, that will be a good thing. They are a cancer. But they are integral to Russia's geopolitical influence as a proxy for military force. Russia isn't going to give them up without an alternative.
