More Units Assigned to 10th Army Corps

Three units have been found to have been under the command of the 10th Army Corps of the Ukrainian Ground Forces, with two being recently assigned. This was confirmed by the corps’ official Facebook page. The new units that have been assigned are the 14th Mechanized Brigade, the 1st Medical Battalion, and the 183rd Reserve Battalion. On July 12, 2025, MilitaryLand also reported that the 43rd Mechanized Brigade entered service with the 10th Army Corps.
About the units
The 14th Mechanized Brigade was previously under the direct command of Operational Command West. The brigade was formed in 2014, based on the 51st Mechanized Brigade, and has been active in combat operations since its inception. Following the full-scale Russian invasion, the unit was deployed to Kyiv Oblast to help block a potential Russian advance to the west. It later took part in the Kharkiv offensive and, since 2023, has been holding the line near Kupyansk.
The 1st Medical Battalion was previously known as the Medical Service of the International Legion in the Ukrainian Ground Forces, being reformed and expanded as a separate unit on February 5, 2025. The battalion is composed predominantly of ethnic Ukrainians. It becomes the third corps to have its dedicated medical battalion, with the others being the 4th Medical Battalion inside of the 3rd Army Corps, formed on the basis of the Medical Service of the 3rd Assault Brigade, and the 2nd Medical Battalion subordinated to the 12th Army Corps stationed in Kyiv.
Additionally, the 183rd Reserve Battalion, which was discovered by MilitaryLand back in March 2025, is under the command of the corps. This was confirmed with the corps posting that soldiers of the battalion completed a foundational course, with more to come.
