Mikhail Nagamov, 41, the commander of a sapper regiment, died fighting in Ukraine on April 13, Russian media has reported, without saying where or how exactly he died.
His death is just the latest in a string of high-profile deaths for the Russian military, coming on the heels of seven generals already killed in action since the war began and staggering losses overall.
