With its transfer to the Waffen-SS, the brigade was renamed to Waffen-Sturm-Brigade RONA, and Kaminski gained the rank of Waffen-Brigadeführer der SS (the only man with such a rank). After Operation Bagration (June to August 1944), the RONA retreated further west, and by the end of July 1944, the remains of the Kaminski unit (3 to 4 thousand—some sources estimate 6 to 7 thousand) assembled at the SS training camp Neuhammer. On the base of the Kaminski unit, SS leaders planned to form an SS Division – 29.
