Russian private military companies are reportedly forming combined units with airborne elements due to significant losses in manpower. Denaturing elite airborne units with mercenaries is shocking, and would be the clearest indication yet that Russia has exhausted its available combat-ready manpower reserves. The Russian 810th Guards Naval Infantry Brigade is reportedly receiving personnel from other Black Sea Fleet units, including navy ship crewmembers. Newly formed or regrouped units are unlikely to be effective in combat.
