49th Assault Battalion Carpathian Sich is a volunteer unit of the Ukrainian Ground Forces. The unit was originally created as the Carpathian Sich detachment by Oleh Kutsyn in 2014. The unit was deployed to Pisky in 2014 and remained there until 2016.
During the defense of Pisky and Donetsk Airport, the unit made close ties with the 93rd Mechanized Brigade and joined its ranks in 2015 as Assault Company Carpathian Sich. All soldiers signed a contract with Ukrainian Army, and the unit was legalized. After the withdrawal of the 93rd Mechanized Brigade from the ATO zone in 2016, Carpathian Sich was disbanded without the knowledge of its members, claiming that an independent formation cannot be part of regular army units. All unit members wrote dismissal instead of joining various parts of the brigade.
On February 24, 2022, when Russian forces launched a full-scale invasion, Volunteer Battalion Carpathian Sich was created again. On May 19, 2022, the unit joined the Ukrainian Army as the 49th Separate Rifle Battalion.
On June 19, 2022, the founder and commander Oleh Kutsyn, was killed near Izium. In 2023, the rifle battalion was reformed into an assault battalion.
