The 10th Brigade was an infantry brigade of the Australian Army. Originally formed in 1912 as a Militia formation, the brigade was re-raised in 1916 as part of the expansion of the Australian Imperial Force following the end of the Gallipoli campaign. It subsequently saw service on the Western Front in France and Belgium during World War I. After the war it was disbanded but was re-raised in 1921 as a part-time formation based in the state of Victoria. During World War II the brigade was used in a garrison role in Australia before being disbanded in 1942. The brigade is slated to be re-raised as the Army's 'Fires Brigade' to host and operate the Australian Army's High Mobility Rocket System (HIMARS) and National Advanced Surface-to-Air Missile System (NASAMAS)
