Russians have their own Chechens also fighting for them in Ukraine.
Indeed. The Vostok BN is largely comprised of Chechens. Fought at Donetsk, and elsewhere. Kadyrov promised to send more if needed. However, Chechens don’t play well with Russians and soon many fights broke out between Russians/Chechens. Many have been pulled back now.
A little food for thought to those in the Chechen cheering section: They were in Iraq fighting against us and killing/raping children at Beslan.
