Help to identify photo. Possibly Ukraine 1942?

I am curious to find out a little more about this photograph. Can anyone help identifing the uniforms and the man in the middle? It was found in a second hand book, “Harvest of Despair” by Karel C. Berkhoff which is a book about Second World War Ukraine.

Many thanks in advance.
