The family of T-54/T-55 medium tanks was developed by the Soviet Union after the end of the Second World War. Like the famous T-34, the design was characterized by several fundamental features: simplicity, effectiveness, low production costs, and ease of repair on the battlefield. These characteristics quickly accelerated its spread throughout the Warsaw Pact countries, as well as in many other nations across Asia and Africa. The T-55 tank, which can be considered one of the most famous post-war MBTs, was in fact an evolution of the T-54, incorporating an improved engine, increased ammunition capacity, and more effective NBC protection. Armed with a 100 mm gun, it was provided with effective armor protection, bringing its overall weight to 35 tonnes. It remained in service for decades across numerous operational theatres, becoming one of the most widely used armored vehicles in military history.
