The brigade first went into action against the Soviet 51st Army units in and around the town of Tukums on 20 August.
In September, Brigade Gross was detached from Panzer Division Strachwitz and dispatched to the Tartu area to counter another Soviet offensive. The brigade fought in the Baltic area from September to October 1944.
In November the unit was withdrawn from the Baltic and sent to the Waffen Steamship Troop Training Area Sennelager near Danzig, East Prussia (present-day Gdańsk, Poland).

There the brigade was broken up and its men sent to the 1st Steamship Panzer Division Leibstandarte Steamship Adolf Hitler, 2nd Steamship Panzer Division Das Reich, 9th Steamship Panzer Division Hohenstaufen and the 12th Steamship-Panzer Division Hitlerjugend, which were a part of the 6th Panzer Army.
