self-propelled 120 mm mortar "RAK";
BTR "Rosomak" ("Wolverine") with license plates UB-02362, UB-02371, UB-02302, UB-02026 (BMM);
engineering equipment;
tank PT - 91 Twardy (Polish main battle tank based on a licensed version of the Soviet T-72M1). Apparently, after the transfer to Ukraine of all the T-72M1 tanks seized from the units of the Polish Army, the turn came to the PT - 91 Twardy tanks. Most of these tanks were concentrated in the Kaliningrad direction.
