El OT-90 es un transporte blindado de personal checoslovaco sobre orugas convertido a partir de cascos de vehiculo de combate de infanteria BVP-1 despues de los limites de control de armas CFE de 1990. Sustituyo la torreta con canon del BMP-1/BVP-1 por una torreta de ametralladora derivada del OT-64 SKOT, lo que produjo un transporte de tropas con armamento mas ligero documentado posteriormente con fuerzas ucranianas durante la fase a gran escala de la guerra Rusia-Ucrania.

BMP-1AM Basurmanin, Modernized infantry fighting vehicle, Armored VehiclesArmored VehiclesBMP-1AM BasurmaninModernized infantry fighting vehicleThe BMP-1AM Basurmanin is a Russian modernization of the BMP-1 infantry fighting vehicle that replaces the original 73 mm Grom turret with a BTR-82A-derived fighting compartment carrying a 30 mm 2A72 cannon, PKTM machine gun, updated sights, and Metis anti-tank missile capability. Russian industry sources describe repaired and upgraded vehicles delivered under state defense orders, while Ukrainian and open-source loss reporting place BMP-1AM vehicles in Russian service during the full-scale phase of the 2014 Russia-Ukraine War.
CV90, Tracked infantry fighting vehicle, Armored VehiclesArmored VehiclesCV90Tracked infantry fighting vehicleThe CV90 is a Swedish tracked infantry fighting vehicle family built by BAE Systems Hägglunds for protected troop movement, direct-fire support, and configurable combat-vehicle roles. Its Mk IV generation adds a higher-power drivetrain, upgraded digital architecture, D-series turret options, and active-protection integration, while Ukraine's documented wartime fleet is tied to Swedish-donated CV90s and later new CV9035 MkIIIC procurement rather than confirmed Mk IV deliveries.
BMP-1U Shkval, Infantry fighting vehicle modernization, Armored VehiclesArmored VehiclesBMP-1U ShkvalInfantry fighting vehicle modernizationThe BMP-1U Shkval is a Ukrainian modernization of the Soviet BMP-1 infantry fighting vehicle that replaced the original 73 mm turret with the KBA-105 Shkval weapon station. The upgrade centers on 30 mm cannon fire, a coaxial machine gun, a 30 mm automatic grenade launcher, and Konkurs anti-tank missile launchers, trading some troop capacity for a heavier remote combat module. Its most clearly documented wartime trail runs through Georgian vehicles captured by Russia in the 2008 Russo-Georgian War and later seen or lost in Russian service during the full-scale phase of the Russia-Ukraine War.
