Footage of two Ukrainian M113 armored personnel carriers attempting to break through near Kupyansk and being engaged by Russian FPV drones. The APCs are equipped with the homemade "Tsar-Mangal" armor and reinforced "Dikobraz" armor, also known as "Hedgehog." This same armor is used by the Russian army. M113 armored personnel carriers have been produced in the US since 1960; a review of them is available on the channel. The armor of the APCs withstood several strikes by Russian FPV drones, but the rear of the APCs was partially protected. As a result of the Russian drone attacks, the crews abandoned the APCs and attempted to hide behind the combat vehicles. The video was filmed by drones of the 6th Army of the Russian "Zapad" group.
