Homeland of Cranes: Fighting fire

This short documentary was shot last May for and about Russian volunteer firefighters. These are the same volunteers, who were under criminal, state and informational attack recently, when they came to southern Russia to fight forest fires: https://www.washingtonpost.com/world/masked-attackers-beat-greenpeace-firefighters-in-russia/2016/09/09/b81051af-ee75-4351-a0fa-3deb7621b43e_story.html (and many another articles).
Last spring I spent a few days with them, when they were on duty in nature reserve «Homeland of Cranes» (www.craneland.ru), fighting grass fires. I volunteered as a vehicle driver, shooting video every free minute. In this documentary they tell what they do and why.
