All known Army Corps as of April 2025

The Ukrainian Defense Forces are actively transitioning to a corps-based structure, with plans to establish between 18 and 20 corps, including those that existed prior to the reorganization. Each corps will generally consist of approximately five mechanized brigades, an artillery brigade, and specialized units for air defense, engineering, reconnaissance, communications, and unmanned systems operations.
Below is a list of all known corps, including some that have not been officially confirmed but have been revealed through various sources.
National Guard
The National Guard of Ukraine has formed two army corps based on two high-performing units—the 12th Azov Brigade and the 13th Khartia Brigade. Although the National Guard includes many other units, there are currently no plans to establish additional corps formations.
Ground Forces
The Ground Forces serve as the primary branch for the formation of army corps. Currently, twelve army corps formations are known, with an additional three to five expected to be established. According to information obtained by MilitaryLand, these new corps are likely to continue the existing numerical designation sequence.
One of the corps formations is expected to include the 24th Mechanized Brigade, the 54th Mechanized Brigade, and the 56th Motorized Brigade. However, not all brigades will be incorporated into the corps structure—some will remain under the direct command of the General Staff or the Ground Forces Command. According to sources from MilitaryLand, the 19th Missile Brigade is one such example.
Naval Forces
The Naval Forces of Ukraine currently have one corps—the 30th Marine Corps, commanded by Maj. Gen. Dmytro Delyatsky. Despite comprising four marine brigades, three coastal defense brigades, and two artillery brigades—making it the largest corps in the Defense Forces by number of units—there are no plans to establish additional corps within the Naval Forces.
Territorial Defense Forces
According to Ukrainska Pravda and earlier reports, the Ukrainian Command plans to establish at least one additional army corps.
Air Assault Forces
Before the transition to the corps system, the Air Assault Forces operated a single corps—the 7th Rapid Reaction Corps. As part of the reorganization, a second formation was introduced: the 8th Air Assault Corps, built around the 82nd Air Assault Brigade.
Each corps will be assigned a designated zone of responsibility, typically covering a 50 to 70 kilometer stretch. Considering the active front line currently extends approximately 1,200 kilometers, this distance is roughly equivalent to the segment between Bilohorivka in Luhansk Oblast and Chasiv Yar in Donetsk Oblast.
