Direct proof of use
The T-64BV is directly documented in the 2014 Russia-Ukraine War through three evidence streams: 2014 reporting that attributed T-64 tank transfers to Russia-backed separatist forces, Ukrainian military reporting on T-64BV crews conducting combat firing tasks, and Oryx visual-loss lists that identify T-64BV tanks among Ukrainian and Russian-side losses in the full-scale invasion.
For Ukraine, ArmyInform interviewed a T-64BV company commander in the 157th Separate Mechanized Brigade in April 2025. The commander said the unit was working on T-64BV tanks near Pokrovsk and described direct-fire and closed-position fire missions. Defense Express separately reported a Ukrainian Military Television segment on modernized T-64BV 1K command tanks carrying out combat tasks after a 2022 modernization.

Timeline
In June 2014, U.S. officials said three T-64 tanks and other military vehicles had crossed from Russia into Ukraine near Snizhne, while Reuters and AFP reporting carried by ABC also described video evidence and U.S. assessments that separatists had acquired Russian tanks and rocket launchers.
After the February 2022 full-scale invasion, open-source visual documentation shows large numbers of T-64BV losses. Oryx lists Ukrainian T-64BV tanks as destroyed, damaged, abandoned, and captured, and separately lists Russian-side T-64BV losses, indicating use and battlefield circulation on both sides of the expanded war.
By late 2023 and 2025, Ukrainian reporting described T-64BV variants in active firing roles: a T-64BV 1K command-tank modernization in combat service, and T-64BV crews near Pokrovsk firing against dugouts, forest lines, and targets from closed positions.

Battlefield role
The documented role is conventional armored combat: frontline maneuver, defensive holding, direct fire, and fire support. Ukrainian sources describe T-64BV crews moving to firing positions, engaging dugouts and tree lines by direct fire, and using closed firing positions at several kilometers when terrain and reconnaissance allowed.
The same sources show how the role changed under dense drone threat. The ArmyInform interview describes additional overhead protection, short exposure at firing positions, night recovery, and coordination with drones after tank fire. Those details support a battlefield role centered on short-duration armored fire missions rather than persistent exposed maneuver.
Russian-side and separatist use is documented most clearly through transfer and loss evidence rather than unit-level tactical reporting. The 2014 U.S.-attributed reports support early separatist acquisition of T-64 tanks, while Oryx lists visually confirmed Russian-side T-64BV losses during the full-scale invasion.
