Grivnik brigade

The Grivnik Brigade was an independent Soviet brigade during World War II. This brigade fought alongside the Soviet 88th Rifle Division against the Finnish J-Group of the Finnish III Corps and the German SS North during Operation Barbarossa. They beat back both forces, forcing the Finno-German troops to retire to the city of Kestenga, near Lake Topozero in September 1941.

Combat Composition of the Soviet Army for 1 September 1941 lists no such formation, but there is a Murmanskaya Rifle Brigade listed alongside 88th Rifle Division in 14th Army (Soviet Union).
