A naval brigade is a body of sailors serving in a ground combat role to augment land forces.
Prior to the Federation of Australia, several of the Australian colonies had their own Naval Brigades with New South Wales also having a separate Naval Artillery Volunteers who manned coast artillery. These units took part in the Boxer Rebellion in China.
During the German Revolution of 1918–19 mutineering sailors of the Imperial German Navy formed the Volksmarinedivision, the best trained and organised force available to the revolutionary socialists they defeated regular army troops and battled the rightwing freikorps over the direction of postwar Germany.
During the October Revolution and Russian Civil War, Bolshevik sailors were involved in storming the Winter Palace. When the Nazis invaded Russia, sailors were diverted from the battleships to aid in the defence of Leningrad and Sevastopol. Throughout the war, Russian naval infantry distinguished themselves in land combat, and eventually earned special forces status.
Within the Royal Navy, a naval brigade is a large temporary detachment of Royal Marines and of seamen from the Royal Navy formed to undertake operations on shore, particularly during the mid- to late-19th century. Seamen were specifically trained in land-based warfare at the gunnery school at HMS Excellent in Portsmouth.
