We identified Russian Army military unit that captured the building of Council of Ministers of Crimea in Simferopol on February 27 2014 at 4:30am. That was 7th Guards Airborne Assault Division, see details about this unit at Wikipedia here And it appears that the paratrooper of this unit who took part in that military operation belongs to one of neo-nazi groups in Russia. His name is Ramenskiy Stanislav. His special forces unit #61756 is part of Russian military intelligence. On April 14 2014 he received a medal “For the return of the Crimea”.

Russian neo-nazi paratrooper Ramenskiy Stanislav in front of Council of Ministers of Crimea in Feb 2014
During the investigation of Russian Army involvement in the military conflict on the East of Ukraine our team has located social profile of Stanislav Ramenskiy https://vk.com/mixmake. He is using nickname “Svyatoslav Mudry”. The photo above was taken right after the building of Council of Ministers of Crimea was captured by heavily armed military unit without any identification marks. The building behind Ramenskiy was identified as the building of Council of Ministers of Crimea. He uploaded that photo only on July 6 2014 few months after the annexation of Crimea by Russian Federation. The photo is in high resolution 2560 × 1714.
On March 1 2014 Crimean news agency posted several photos with armed men who took the building of the Council of Ministers of Crimea, see their post here http://www.kianews.com.ua/news/centr-simferopolya-polnostyu-okruzhen-voennymi So this is pretty clear when and where the photo posted by Stanislav Ramenskiy was taken.
On July 16 2014 Stanislav Ramenskiy uploaded a photo of a medal he received from the Ministry of Defense of Russian Federation. In the document it says that the order was issued on April 14 2014. The medal says “For the returning of Crimea”. The order is signed by the commander of his military unit #61756 Maj.-Gen. V.Solodchuk. The full name of the unit is 7th Guards Airborne Assault Division. Valeriy Solodchuk is the commander of that division since 2012. Military unit #61756 is stationed in Novorossiysk. You can see it marked on Wikimapia here The photo of the medal is also in high res 2560 × 1920
His military unit number can also be identified from his profile, he even specified the years of service! And the name of his squad – “Intelligence Squad of Division”
Below is another photo high res 2560 × 1920 photo that Stanislav Ramenskiy uploaded on August 20 2014. In the photo he is holding a flag of Russian Army Military Intelligence special forces. The location where the photo is taken is not identified. In the photo you can see a tattoo that is usually made by neo-nazi groups active in Russia.
In the photo there is a silver chain on his neck. But it’s not just silver chain. There is medallion attached to it that you can see in another photo that Ramenskiy uploaded on August 27 2014. In the comments to the photo he wrote “Finally I got it. Thanks a lot”. The symbol on the medallion is used by ultra-right groups in Russia that positions themselves as pagans, but who are actually are neo-nazi.
There are also other photos at his profile that don’t need any comments, like this one with swastika.
Or another photo with symbols of Russian neo-nazi group. The text in the picture says “The World will be WHITE”
There are many other Russian special forces soldiers who took part in military actions in Ukraine and who are already identified. But this one is very ironic. Russian neo-nazi who joined Russian Army and went to “liberate” Crimea posting photos of his medal he got from Putin for the military operation that Kremlin did deny for over a year.
