Ukrainian tank with Slovak barrel

Ukrainian armored troops despite the failure of hundreds of tanks further based on structures equipped with smooth-bore cannons of the russian 125 mm (family T-64/72/80 and its derivatives). This makes access to parts and components of which production in the allied countries (mainly western countries) is limited. Nevertheless, there are countries with industrial capacity to manufacture components for Soviet/Russian standard equipment, e.g. tank barrels in a 125 mm caliber.
