History

War in Donbas

Main article: Russian people's militias in Ukraine

The 1st Army Corps was formed on 12 November 2014 as an effort to unite numerous volunteer units under one command. Considered by Ukrainian and Western analysts as a formal part of the Russian 8th Combined Arms Army, it nevertheless had a certain degree of autonomy.

The corps was deployed along the contact line that stretched from the coast of the Sea of Azov to the LPR border north of Debaltseve, where it met with the 2nd Army Corps.^[6]

Russian invasion of Ukraine

The corps played an active role in the Russian offensive in Southern Ukraine, taking part in the battle of Volnovakha and siege of Mariupol.

In January 2023, it was officially incorporated into the Russian Armed Forces and became part of the 8th Combined Arms Army.

In the summer of 2024, the 1st Army Corps was reorganised into the 51st Combined Arms Army.^[5]

On September 18, 2024, the 51st Army was awarded the honorary designation "Guards".^[7]

Operations in Kherson Oblast

A member of the DPR's 109th Regiment was accused of rape during the occupation of the village of Krasnivka (uk), Kherson Oblast, in March 2022.^[8]

In July 2022, the 109th, 113th, and 125th Regiments of the DPR were deployed to Zolota Balka, Davydiv Brid, Arkhanhelske, and Vysokopillia in the Kherson Oblast, according to Russian military documents published by Ukrainian officials. In late August 2022, amid a Ukrainian counteroffensive in the Kherson Oblast, Ukrainian military officials claimed that the 109th Regiment had left its positions.^[9]
