"Finally, it is time when all Aidar fighters have passed collective combat training and returned to the front with renewed energy and skills to protect their native Ukraine," the message reads.
The fighters will hold the second line of defense in the Donetsk region.
"Unfortunately, we have not returned to the Luhansk region, and for the moment, we will hold the second line of defense in the Donetsk region. The HQ is already operating, soldiers are building defenses and getting settled, and the Ministry of Defense has finally provided fighters with winter clothing and footwear," Lykholit said.
