The NUG claims that according to their records in the time period between July 2024 and August of 2026 Junta casualties were:

20,383 killed
9,792 wounded
Approximately 23,874 deserted or defected
536 are currently POW's

This would all equal to roundabout 55k casualties in the last two years, with the conflict ongoing since 2021

Note that these figures are their official confirmed records and as with any military may be inflated, however they may also be an undercount due to only confirmed casualties counting, which is why there are such specific numbers, and there may be more unconfirmed casualties
