The pakistani t-80uds (objekt 478BEH) were all new builts except the first 15 vehicles that were also brought to the same standard. Ukraine does not operate the type and are happy with using/ upgrading their t-64s. They only have some T-80BVs in storage.Let Pakistan to buy them first...it's possible for Pakistan to opted for older T-80UD...many of these tank are in Ukrainian storage..and Pak also have 300 something T-80...so they can go for numerical value and bring the T-80 storage to pak..and with chinese or ukrainian help upgrade them...
