The 3rd Army Tank Brigade was an Australian Army brigade of World War II. The Brigade was formed in May 1942 by bringing together three armoured regiments which had previously formed part of the 1st Cavalry Division. As with all British Commonwealth Tank Brigades, the primary role of the 3rd Army Tank Brigade was to provide armoured support to infantry formations and the Brigade was initially equipped with Matilda II infantry support tanks. Some of the Brigade's Matildas were later replaced with M3 Grants. While the 3rd Army Tank Brigade was gradually disbanded between August and September 1943 two of its two tank battalions were retained as independent battalion groups until they were also disbanded in September 1944.
