Equipment designated for the 3rd Army Corps was shipped in late August 2022 to
Neklinovka station in northwestern Rostov Oblast, close to the Ukrainian border and the
Sea of Azov, to prepare for deployment to the
Donbas front. As a result of the Ukrainian counteroffensives
in southern and
northeastern Ukraine, the volunteer battalions of the 3rd Army Corps were deployed piecemeal to reinforce the Kherson, Kharkiv,
Melitopol, and
Mariupol sectors. On September 9, during the
Ukrainian Kharkiv counteroffensive, footage appeared of a military column with 3rd Army Corps markings headed towards the front in
Kharkiv Oblast. Afterwards, reserves and equipment of the 3rd Army Corps were reportedly moved to reinforce units in
Donetsk Oblast and
Zaporizhzhia Oblast. Part of the Corps fighting in the failed February Russian attack on
Vuhledar. According to UK intelligence, the 10th Tank Regiment lost as many as sixty of its seventy tanks around
Avdiivka in the Donetsk region in March when they kept repeating frontal attacks that had proved to be a failed tactic elsewhere. The Corps was then met by the
2023 Ukrainian counteroffensive. During the recapture of
Andriivka in mid-September, the Ukrainian
3rd Assault Brigade encircled and claimed to largely destroy the Army Corps'
72nd Separate Motor Rifle Brigade. According to a report by
Forbes, "in two days of hard fighting, the 3rd Assault Brigade claimed it killed the chief of intelligence of the 72nd MRB [Motor Rifle Brigade], many of the Russian brigade's officers and 'almost all the infantry'. Russian casualties—dead, wounded and captured—could number a thousand or more." In the summer of 2023 the 3rd Army Corps moved under the command of the
Central Military District and became a more formalised unit, rather than a loose collection of volunteer units, before being deployed to the Kharkiv-Luhansk Oblast area. == See also ==
