The brigade was formed on the basis of the 150-та механізована бригада.

In 2024, units of the brigade were deployed across multiple sectors, units carried out combat missions in the Sumy and Kharkiv regions, as well as in the Donetsk region. During fighting in eastern Ukraine, brigade personnel took part in defensive operations in the area of Toretsk.

Since the beginning of 2025, the brigade has been continuously engaged on the southern axis, particularly within the Kherson and Mykolaiv regions.

On March 1, 2026, the brigade was reformed into a Marine Brigade.
