|The Orenburg dance school video has been a huge YouTube hit|
Prosecutors had said their "erotic and sexual twerk dance" was disrespectful to historic memory and unacceptable.
Earlier this month, Russian officials closed a dance school (Orenburg) after a similar dance video emerged on the internet.
The latest incident involves six dancers - one of them a minor who was not convicted - who had posted a video on YouTube.
"This incident of disrespect for the memory of war history is unacceptable and any attempts to desecrate sites of military glory will be stopped immediately," prosecutors said.
Aside from the questionable, old Soviet attitude that the military can produce glory, the memorial represents soldiers who laid down their lives for their country. Twerking was not the image of the country they had in mind when they went to fight. Having their memory used and abused in a vulgar, dance video is beyond contemptible.
The sentences come as Russia prepares to mark the 70th anniversary of the World War Two victory.
They also follow the incident early in April when a video clip from the Orenburg dance school on YouTube was viewed millions of times.
The video clip, entitled Winnie the Pooh and the Bees, showed a group of teenage girls dancing on stage in striped leotards, long socks and mini-skirts,
They perform hip-thrusting moves characteristic of twerking. Not to mention sex.
A committee is investigating whether the performance amounts to negligence or even "debauched action", which is punishable by a range of sanctions from community service to three years behind bars.
Thank you Miley Cyrus for taking vulgarity to another level. Can there be anything worse in society than a fallen Christian?
