Ukraine's Armed Forces begin transition to corps structure
General Oleksandr Syrskyi, Commander-in-Chief of the Armed Forces of Ukraine, has announced the beginning of efforts to transition to a corps-based structure.
Before the transition to a corps-based structure, Ukraine’s military operated under a brigade-based system, where brigades functioned as independent units under the control of Operational Commands. This structure was adopted after the disbandment of Army Corps in 2015, when the military shifted to a more decentralized command system.
After Russia’s full-scale invasion in 2022, the need for greater coordination led to Syrskyi’s decision to restore army corps, with the reintroduction of a corps-based structure aiming to improve operational control, integrate larger formations, and align with NATO standards. The transition is also intended to enhance command efficiency and optimize force deployment.
