The T-54/T-55 is a Soviet tank family built around a low-profile tracked hull, four-person crew, and 100 mm D-10-series gun. It became one of the most widely produced tank families of the Cold War, with Soviet and licensed production spreading across Warsaw Pact and partner states. In the Russia-Ukraine War, its renewed appearance with Russian forces has been notable because it illustrates Russia drawing on very old armored reserves for secondary fire-support or positional roles rather than fielding a modern main battle tank capability.
Russian forces were reported moving T-54/T-55-series tanks out of storage in March 2023, and a stock-condition T-54/T-55 was later reported with Russian forces in the Zaporizhzhia area; reporting assessed the tanks as more plausible for fire support, static positions, or other secondary roles than modern tank combat.
Leopard 1A5Main battle tankThe Leopard 1A5 is a German main battle tank modernization centered on improved fire control, thermal sighting, and the 105 mm L7-series gun. In the Russia-Ukraine War, refurbished A5-family tanks from European industrial stocks give Ukrainian armored units a lighter Western tank with good mobility and logistics support, but less passive protection than newer Leopard 2 variants.
M-55SUpgraded T-55 main battle tankThe M-55S is Slovenia's modernized T-55 main battle tank, rebuilt by ST Ravne with a 105 mm gun, explosive reactive armor, fire-control upgrades, laser-warning equipment, and NATO-compatible ammunition. During the Russia-Ukraine War, Slovenia committed 28 M-55S tanks to Ukraine through a ring exchange with Germany, making the type a legacy Soviet chassis adapted for Western-supported Ukrainian armored forces.
PT-91 TwardyMain battle tankThe PT-91 Twardy is a Polish main battle tank developed from the T-72M1 with domestic upgrades including ERAWA explosive reactive armor, improved fire-control equipment, and an 850 hp diesel powerpack. In the Russia-Ukraine War it represents a Polish-supplied T-72-family tank type used to expand Ukraine's armored force with a familiar three-crew, autoloaded 125 mm platform.
Strv 122Main battle tankThe Strv 122 is Sweden's upgraded Leopard 2 main battle tank, adapted for Swedish service with reinforced protection, Swedish communications, smoke launchers, and a four-person crew. Sweden transferred ten tanks to Ukraine in 2023, pairing the donation with training for Ukrainian crews before the vehicles were fielded in the Russia-Ukraine War.
T-62Main battle tankThe T-62 is a Soviet main battle tank built around a 115 mm smoothbore gun, a four-person crew, and conventional tracked armor layout. Designed by the Uralvagonzavod design bureau as a successor to the T-54/T-55 family, it became a major Cold War Soviet tank and later reappeared in Russia's war against Ukraine as older T-62M and T-62MV variants were pulled from storage to supplement Russian armored forces.
T-80Main battle tankThe T-80 is a Soviet-designed main battle tank built around a compact three-man layout, autoloaded 125 mm gun, and gas-turbine mobility in most major variants. In the Russia-Ukraine War it appears on both sides: Russia has deployed T-80BV, T-80U, and T-80BVM-family tanks, and Ukraine has operated captured Russian T-80s alongside its own armored forces.
