Ukraine war: Russia goes back to prisons to feed its war machine
The Russian defence ministry has been recruiting prisoners to fight in Ukraine, apparently taking over from the Wagner mercenary group which was the first to adopt the practice last year.
Such army units are commonly known as Storm-Z, the letter Z being one of the symbols of Vladimir Putin's so-called "special military operation" against Ukraine. It is also the first letter of the Russian word "zek", or "inmate".
The name Storm-Z is unofficial and can be applied to a range of Russian army units active in different parts of Ukraine....
