The MT-LB armored personnel carrier has always been susceptible to various types of modifications or upgrades, both factory-made and with the aid of ad hoc or improvised solutions. Many of them appeared during the war in Ukraine, and the top strength of the appearance of improvised combat vehicles based on the MT-LB falls in the last year. 1 example was captured by the Ukrainians in early February in battles against soldiers belonging to the 1st Corps of the alleged “Donetsk People's Republic”, incorporated by Russia into the composition of its armed forces after the illegal annexation of Ukrainian oblasts.
