The Sich Battalion officially became an active unit of Ukraine's Ministry of Internal Affairs following its oath taking ceremony on 26 August 2014, and is composed of around 50 volunteers, some of whom have prior military service.

While the Sich Battalion was much smaller than other volunteer units, it was designed for the specific purpose of combating insurgents in the 2014 pro-Russian unrest in Ukraine.

According to the press service of the battalion, part of the unit is located in the Donetsk region near Kurakhovo, where it performs tasks to protect the dam of Kurakhiv TPP.
