Wagner Group chief, U.S. election interferer, and onetime convict Yevgeny Prigozhin did something unusual, even for him, on Wednesday: he published a photo of Wagner’s losses in Ukraine.

It’s a graphic image, showing a ditch full of corpses mutilated by what appear to be military-grade weapons. But Prigozhin used it to reinforce a complaint that he’s been making over the past week: the Russian Ministry of Defense has stopped giving his mercenary army the ammo it needs to keep fighting.
