Dmitiry Skogerov is Russian and instructor in the art of Systema (Russian Martial Art). He lives in Novosibirsk, Novosibirsk Oblast, Russia. He is masterful in the way he approaches the various issues of combat. What drew me to him and to study his approach via his videos is that he approaches combat in a simplified manner. His web address is https://www.rmasv.ru/ or https://vk.com/sibviun. Enjoy!
