Ustinov, Special Forces & Chechnya Vet

[Khmelnytsky]

I remember watching one of Ustinov's old K-1 fights (not sure which one, i think the announcer was british or aussie) and them mentioning he was a member of the special forces in the Russian military and that he fought in Chechnya. He lives in Belarus but i know he was born in Russia

Anyone have any info on this or can confirm it?
