Despite the media impression, a lot of it Wagner's fault, Wagner is not alone around Bakhmut. There are units of Russian Aerospace aka paratroopers aka Spetnaz, along with select units of the LPR and DPR. They solidify the flanks, provide artillery support and cover the logistics. Russian Aerospace are located around the south of Chasov Yar. The paratroopers were behind the defense of Kherson, and most notoriously, the fire trap known as the Penis of Kherson. So the non Wagnerites in the area, all know to play defense.
Also the fronts in Limansky, Kupyansk, Avdiivka, Seversk, Kremennaya, Marinka, and even in Ugledar are flaring up and intensifying. They are going to draw reserves one way or another from the AFU. I am especially looking at Avdiivka, which has vulnerable supply lines and is also in a nasty pincer.
