 After the Battle of Brunete, the brigade was reorganized into a new Spanish division, known as the División de Ingenios Blindados (Armored Vehicles Division). This was composed of a tank brigade and an armored brigade; the latter was made up of lighter armored fighting vehicles, such as the BA-6. It was put under the command of Spanish Colonel Sánchez Paredes. By this time, most of the Soviet tankers had returned to the Soviet Union to provide information on mechanized warfare in Spain. The only Soviet unit left was the heavy tank regiment, armed with brand new BT-5s which had not been used in combat yet. This regiment was crewed by both Soviet and veteran Spanish tankers, and was put under the command of Soviet Colonel Kondriatev. Finally, the division also disposed of an infantry brigade and an anti-tank artillery company. However, by this time the Republican military command had relegated the tank to the role of merely infantry support, dissuaded by the poor performance of Republican armor to that date. The last major battle Republican armor would take part in was the Battle of the Ebro, in 1938.
