Based in an office behind a lingerie store in the Mongolian capital, the shaven-headed, jackbooted Tsagaan Khass stormtroopers launch raids on mining projects, demanding paperwork or soil samples to be studied for contaminants.

“Before we used to work in a harsh way, like breaking down doors, but now we have changed and we use other approaches, like demonstrations,” the group’s leader, Ariunbold Altankhuum, 40, told Reuters, speaking through a translator.

On a patrol to a quarry two hours from the capital, members wore black SS-style Nazi uniforms complete with lightning flashes and replica Iron Crosses…

“Today our main goal is to save nature. We are doing things to protect the environment,” Altankhuum said. “The development of mining is growing and has become an issue.”
