After 24 February 2022, the corps was committed to the
Russian invasion of Ukraine. On 26 October 2022, Reuters published a special report regarding the defeat and retreat of an 11th Army detachment under colonel Ivan Popov and thousands of documents left in a base in Balakliia after the Ukrainian eastern
Kharkiv counteroffensive 6–8 September. According to the documents, units within the corps had suffered heavy losses around Balakliia. In an action near Hrakove on 19 July, thirty-nine men were wounded, seven were dead, and 17 were reported missing, with a tank and two APCs lost. Meanwhile, on 24 July, 12 marines were killed in a
HIMARS strike. By 30 August, the corps was down to 71% of its authorized strength, although more draftees were ordered. Some units were even worse off. The 2nd Assault Battalion had 49 personnel, when it should have had 240. The 9th
BARS Brigade, an irregular unit, was at 23% of its intended manpower. In October 2022 American
military correspondent David Axe claimed that the 11th Army Corps was destroyed during the
2022 Kharkiv counteroffensive, having lost half its troops and 200 vehicles, and would "almost certainly require many months to rest, re-equip and induct draftees in order to regain even a fraction of its former strength." In May 2024, it was reported that the 11th Army Corps was taking part in the
2024 Kharkiv offensive. On 16 May, the Ukrainians claimed that two of the 11th Corps’ combat formations, deployed to the Kharkiv sector, the 138th Motor Rifle Brigade and 7th Separate Motor Rifle Regiment – part of the
18th Motor Rifle Division – took 70 percent losses in less than two weeks and had been rendered "combat ineffective". ==Structure==
