Members of the Ukrainian Border Guard utilize a drone and an MT-12 anti-tank gun to slam Russian troops, vehicles, and positions in an unknown part of Ukraine.

Fun fact, the Ukrainian Border Guard is an independent special law enforcement unit. Primarily they are currently stationed near the border with Belarus, but this video indicates that they are also operating near the border with Russian forces as well. They appear to be delivering swift deportation letters to any Russian troops who end up in their sites.
