- Russia is reinforcing its military presence in Ukraine, establishing a separate occupation force through the deployment of Rosgvardia units. The three newly formed regiments of Rosgvardia's 116th Special Purpose Brigade have been deployed to occupied Donetsk Oblast, involving the likely movement of up to 6,000 troops from Russia. This move is likely aimed at hindering Ukraine's counteroffensive efforts, establishing permanent control over occupied regions, and suppressing partisan activity without tying frontline troops to occupation duties.
- The Russian Black Sea Fleet's 810th Naval Infantry Brigade edited its acknowledgment of using chemical weapons in Ukraine, potentially to conceal evidence of a violation of the Chemical Weapons Convention. On 22 December, the brigade stated on its Telegram channel a 'radical change in tactics' involving dropping K-51 grenades from drones onto Ukrainian positions in Krynky, located on the eastern bank of Dnipro river in Kherson Oblast. These grenades contain CS gas, prohibited under the Chemical Weapons Convention as a method of warfare. The brigade removed the specific mention of the K-51 grenade.
- EU's top diplomat, Josep Borrell, asserts that Russian President Vladimir Putin is not pursuing a limited territorial victory in Ukraine but intends to continue the war until achieving a 'final victory.' This aligns with ISW's assessment that Russia is not seeking a ceasefire or genuine negotiations but maintains maximalist goals for a complete victory in Ukraine.
