The 11th Army Corps (Ukrainian: 11-й армійський корпус) is a Corps of the Ukrainian Ground Forces.

History

The 11th Army Corps was established as part of the ongoing military reforms within the Armed Forces of Ukraine. According to available information, Ukraine formed the 9th and 10th army corps and restructured its Reserve Corps to the 11th Army Corps in 2023.[2] This shift intends to modernize the army and bring it closer to NATO standards, as emphasized by President Volodymyr Zelensky when he approved the plan for this reorganization.[3][4]

In July 2025, it was reported that Ukraine's Luhansk operational-tactical group had been reformed into the 11th Army Corps, including the 54th Mechanized Brigade and the 81st Airmobile Brigade operating near the city of Siversk in the Donetsk region.[5] Later that month, it was reported that the corps included the 24th Mechanized Brigade, which was operating at Chasiv Yar.[6][7][8]

Throughout August and September 2025, it was reported that the 11th Army Corps was involved in combat in the Siversk front near the Serebrianka forest and the village of Hryhorivka.[9][10]

In September 2025, the Ukrainian military announced that the 11th Army Corps had repelled Russian incursions near Yampil in the Donetsk region.[11][12][13]

On 27 December 2025, Ukrainska Pravda reported that the corps was removed from operational control of the Siversk front after failing to identify false reports provided by the command of the 54th and 10th brigades, which resulted in the loss of Siversk.[14]

As a consequence of that, Brigadier General Serhiy Sirchenko was dismissed from his command on April 11th 2026. He was to be succeeded by Brigadier General Olesiy Maistrenko, former commander of the 169th Training Center.[15]

Structure

As of 2026 the corps is known to include the following brigades:[16]
