The regiment has faced criticism for its alleged ties to far-right and neo-Nazi groups and its use of symbols associated with Nazism, such as a black wolfsangel logo.
The regiment's founder and former commander, Andriy Biletsky, is also the leader of a political party called National Corps, which advocates for nationalist and anti-immigrant policies.
The U.S. State Department has labeled National Corps a "nationalist hate group" in 2018.
