3rd Army Corps (Russia)

The 3rd Army Corps (Russian: 3-й армейский корпус) is a military formation of the Russian Ground Forces formed in June 2022 to participate in the 2022 Russian invasion of Ukraine. The 3rd Corps was raised in response to the depletion of trained manpower during the early months of the invasion. It was formed exclusively by volunteers, as at that point Russia had not yet begun the process of partial mobilization and preferred to avoid or delay doing so. Recruitment was on a regional basis, with federal subject administrations and local authorities conducting recruitment campaigns. Its current effective strength estimated at 15,500–60,000 personnel as of January 2023, and originally belonged to the Western Military District, before moving under the command of the Central Military District in 2023.
