These are Russian girls who are military cadets from academies after their match on the Red Square at the Parade on the 24th of June. The video is extremely telling in terms of fundamental, increasing, difference in idiosyncrasies between what is known as West and Russians. Especially in relations between girls and guys. I think, that apart being easy on the eyes, it is a very representative sample of a huge cultural difference between West and Russia. This difference is what plays to Russia's strength.
That is why US Embassy in Moscow flying the LGBT flag was received by overwhelming majority of Russians as a public self-humiliation by the US. In Russia, these girls and guys are real elite.
