About Unit

11th Army Corps is a combined arms unit of the Ukrainian Ground Forces.

It was formed in September 2016, acting as a reserve corps and designated as the Strategic Reserve of the Ukrainian Armed Forces.

Following the Russian full-scale invasion of Ukraine, the corps underwent a significant transformation and transitioned into a regular standard army corps. Against this backdrop, the Ukrainian High Command decided to formalise and reform the reserve corps, becoming the 11th Army Corps in April 2024.

In December 2024, Serhiy Sirchenko, who was previously the deputy commander of Operational Command East, was appointed to the command of the 11th Army Corps.

In July 2025, it became known that Sirchenko, who simultaneously commanded Tactical Group Luhansk and the 11th Army corps, would continue to lead operations in the same area around Chasiv Yar and Siversk, now under the direct control of the 11th Army Corps, with Tactical Group Luhansk being officially disbanded.

Insignia

The insignia depicts a shield with a green canvas and a yellow border. At its center is a golden crowned line, commonly known as the Ruthenian lion, also known as the Galician or Ukrainian lion in Ukrainian culture. The lion symbolizes courage, leadership, and other historic ties to Ukrainian history. The lion holds a sceptre, denoting authority and military strength, and over the lion’s chest rests a red shield bearing a stylized symbol.
