The 18th Combined Arms Army (18th CAA) is a field army of the Russian Ground Forces formed from the 22nd and 40th Army Corps in 2023.
The 18th CAA was formed in June 2023 in Crimea as part of the Southern Military District. [1] According to Oleg Marzoev, a reserve officer in the 58th Guards Combined Arms Army, the unit was formed on the basis of the 22nd Army Corps of the Russian Coastal Troops and the newly formed 40th Army Corps. This has come as part of a larger move by the Russian Ministry of Defense to strip ground units away from the Russian Navy, in this case the Black Sea Fleet. As of August 2023, the unit was commanded by Lieutenant General Arkady Marzoev. [2]
Oleg Marzoev claimed that at the time of its formation, the 18th CAA was "one of the largest" units in the Russian army and that the unit was deployed to southern Kherson Oblast. In August 2023, the United Kingdom's Ministry of Defense assessed that the 18th CAA was deployed there to free up more experienced Russian units, namely the Russian Airborne Forces, to redeploy to the western Zaporizhzhia Oblast sector to defend against the 2023 Ukrainian counteroffensive.

Russian sources have reported that the unit has engaged Ukrainian forces near Kozachi Laheri in November 2023. [2] [3]
