Ubited24Media is a Ukrainian news initiative that was established to counter Russian propaganda.  While clearly pro-Ukrainian and pro-Western in its foundations, the agency's reporting has been generally praised as accurate throughout the current conflict.  Today they published a copy of an official Russian document providing a breakdown of casualties for the first eight months of 2025 (thru Aug 31st).  The totals in this document generally align with figures produced by Mediazona (a Russian investigative outlet).  Initial review by  Frontelligence Insight (a respected OSINT group), has concluded the leaked document "appears authentic"
The most significant totals:
KIA            Total  86,744        Officers   1,583  
WIA          Total 158,529        Officers   6,356
Missing    Total   33,966        Officers     Not listed
Captured  Total   2,3111        Officers    Not listed
Total casualties thus for in 2025 are 
281,550
Well over a quarter of a million in just the first eight months of this year.
A couple of additional notes with respect to these numbers.  Due to prisoner exchanges, both sides have been fairly open with each other about prisoners under their control.  That would indicate that a large number of those listed as missing are actually additional KIA.
Secondly, and in keeping with observations of many of us in the West, Russian field medical support is truly appalling.  A KIA to WIA ratio of 1 to 1.8, or if the MIA are included 1 to 1.3  is a medieval warfare statistic.  In Afghanistan, the US KIA to WIA ratio averaged 1 to  9 throughout the conflict. Vietnam was 1 to 4.
