Mariupol , January 2023 During the
2022 Russian invasion of Ukraine, the 501st Battalion of the 36th Brigade was one of the three main Ukrainian units, along with the
Azov Regiment, defending
Mariupol during its
siege by Russian and DPR forces. The battalion was largely destroyed during the course of the siege. On 13 April, the Ukrainian government forces stated that, as a result of a special operation, units of the 36th Marine Brigade managed to connect with the
Azov Regiment in Mariupol. The same day, Russian sources claimed that over 1,000 men of the brigade had been captured, but this remains unconfirmed. The brigade commander, Colonel
Volodymyr Baraniuk, and his chief of staff were among those captured, leaving Major
Serhii Volyna in command of the remnants of the battalion entrenched inside the
Azovstal Iron and Steel Works. The remnants of the unit surrendered on 20 May 2022, along with the remaining defenders of the Azovstal plant.
Mykolaiv While most of the 36th Brigade's units were stationed in Mariupol at the time of the invasion, other elements of the brigade
defended its garrison,
Mykolaiv, during the early months of the
Russian invasion of Ukraine. Later the brigade fought over control of the
Kherson Oblast during the
2022 Ukrainian southern counteroffensive. The brigade took part in the
2023 Ukrainian counteroffensive. On 18 March, two Russian
Kalibr missiles, fired from nearby
Kherson, struck a Ukrainian army barracks in
Mykolaiv housing some 200 soldiers whom were asleep at the time of the attack. Reports from the city morgue and Ukrainian soldiers stated that at least 80 Ukrainian soldiers were killed. It is presumed nearly all 200 soldiers were killed, as only one survivor was pulled from the rubble the next day and temperatures reached below during the night.
Later operations On 19 October 2023, the brigade lost 90 men killed and wounded in a Russian
Iskander strike while attempting to
establish a bridgehead under the
Antonivka railway bridge on the left bank of the
Dnieper, according to a source in the brigade's command interviewed by
Ukrainska Pravda. == Structure ==
