History
The 18th Army Corps was formed as part of Ukraine's ongoing defense reforms. They aimed to improve command structures and operational readiness amid the Russian invasion of Ukraine (2022).[2][3] On April 12, 2025, the commander of the 10th Mountain Assault Brigade, Colonel Roman Darmohrai, was appointed as the commander of the Corps. Darmohray transferred his previous position to the brigadeâs Chief of Staff, Colonel Volodymyr Potyeashkin.[1]
David Axe claimed that the 18th Army Corps was responsible for holding a defensive line in the Sumy region in August 2025, but that its 156th Brigade had been deployed to the Pokrovsk front in September.[4]
