Military Situation In Bakhmut On May 6, 2023 (Map Update)South Front

I would posit that the Excellent Wagner forces are tough and courageous fighters who have been fighting this grueling battle for 6 months.
Prigozhin has been on the front lines for many weeks and he has seen close friends killed and wounded.

It is not surprising to sometimes see him in an emotional state. He cares greatly for his men and this is obvious to see.
He and his men well reserve a rotation rest.
