This is a very interesting chronology of the combat way of this unit, fully photographed with lot's of interesting pictures. The book itself is marked as a "secret". Unit's marked and did not has any existen copies. There is a interesting pictures with their snipers. For example two snipers on the picture Ryazanov and Tzarev, up to the 1st Mai of 1944, kills : Ryazanov 218, Tzarev 142 of the enemies.
If interesting, I will make more pictures
