The 3rd Indian Motor Brigade was formed in 1940 by the Indian Army during World War II. In 1941, the brigade was surrounded at Mechili by Axis forces during Operation Sonnenblume and suffered many casualties breaking out of the encirclement. One cavalry regiment took part in the Siege of Tobruk and then the brigade was reconstituted in Egypt. In August, the brigade, under Brigadier A. A. E. Filose, was re-equipped at Mena in Egypt and in September moved to north-east Syria. In May 1942, during the Battle of Gazala the brigade held a defensive box at Point 171 near Bir Hakeim and was again overrun by units of the Afrika Korps and Italian forces. On 28 May, the remnants of the brigade were sent back to Buq Buq to reform and about 800 of the men taken prisoner rejoined soon afterwards. The Axis had released 600 prisoners from captivity after 48 hours, due to a water-shortage, who reached the Free French fighting the Battle of Bir Hakeim (26 May – 11 June) and another 200 men were liberated by a British column.
In July the remaining units of the brigade were dispersed and allotted to the defence of the Nile Delta. In August the brigade was reformed, less the 2nd Field Regiment RA. The brigade then moved to Sahneh in Iran via Baghdad, under the command of the 31st Indian Armoured Division. In late November, it moved to Shaibah near Basra. The cavalry regiments of the brigade returned to India in January 1943 and were replaced by the 2nd Battalion, 6th Gurkha Rifles, 2nd Battalion, 8th Gurkha Rifles and the 2nd Battalion, 10th Gurkha Rifles, the brigade being renamed the 43rd Indian Infantry Brigade (Lorried).
