The Volunteers supported Imperial Russia, and were part of The ''Samara'' Volunteers of that City. It numbered close to 40,000 Men at Arms. The Flag used was a ''Swallow-Tailed'' Type (Guidon). It featured the three colors of The Bulgarian National Colors (Tri-Color). These bars ranked White, Green and Red. A Gold Imperial Lion was placed in The Red Bar.
