The corps consists of three motorized rifle brigades: one at Zeynalabdin, one at Jusar, and another at an undisclosed location. Unlike the other corps, its role was mainly to serve as a strategic reserve. As a result, it is the smallest corps in the Land Forces Like the 3rd Corps, it will be used for replenishing the ranks of the 1st Corps. At the beginning of the 2020 Nagorno-Karabakh war, Azerbaijan lined up six additional motorized infantry brigades along the front line, with reservists being mobilized and transferred from the 4th Corps. At the Baku Victory Parade of 2020 on Azadliq Square, the corps was represented by a parade contingent led by Colonel Ilham Mammadov.
