I have never seen reenactment photos like these before, especially the last ones.
Ukrainian and Russian reenactors are obviously not only into reenacting Stalingrad and Kursk. The theme of the above reenactment earlier this year was Graz, Austria, 1945. This enabled not only reenactors in Soviet and German kit to participate but also in US and British uniforms.
I had never thought there would be so many US Airborne and British Army reenactors in Ukraine and Russia. Note that one of the "Wiking" reenactors has a Norwegian arm shield.
