MARIUPOL, UKRAINE — The gunner of a Ukrainian BTR-4 fighting vehicle had his helmet cam on when he engaged multiple Russian tanks and APCs in a deadly motorized street fight.


The result is a fascinating look at the high-risk game of modern motorized warfare. Here’s how it happened:


The Telegraph has posted helmet cam footage that was released by the Ukrainian National Guard’s Azov regiment.


The regiment says the footage shows the targeting screen of the gunner of a Ukrainian BTR-4 that was engaging Russian armor in the outskirts of Mariupol in Ukraine.


The footage shows the view through the APC’s gun camera as the vehicle arrives at a street corner and sights a Russian T-72 tank.


The viewer can then see the gunner aiming the vehicle’s 30 millimeter cannon and firing multiple rounds into the tank, as the Ukrainian vehicle slowly backs up to get behind the cover of a house.


In another clip, the same vehicle gets to another street corner, sights a Russian APC, and starts firing shells at it.


Troops can be seen hiding behind the Russian APC as the gunner then aims the cannon to impact in front of the APC, thereby hoping to create deadly shrapnel flying underneath the armored vehicle and hitting the soldiers behind.


The gunner then fires many more shells into the front of the APC, severely damaging it, before speeding off.


The BTR-4 is an amphibious 8 by 8 wheel armored personnel carrier, or APC, designed in Ukraine by the Kharkiv Morozov Machine Building Design Bureau.


Although Ukraine has been fighting back and having many successes, the Russian invasion is still advancing.
