The latest evolution of improvised Russian armor kit appears to include explosive reactive armor bricks placed atop a ‘cope cage.’
Video shows a Russian T-72B3 tank from its Western Military District thundering through the mud with an overhead metal screen, widely termed “cope cage” by Ukrainian troops, with an added layer of what appear to be Kontakt-1 explosive reactive armor (ERA) bricks on top.
The full video from the Russian Ministry of Defense showed the tank providing drone-corrected indirect fire using its 125mm cannon at high elevation. It nearly takes out the drone filming its attack with overpressure from the gun.
Very generally speaking, ERA works to defend against attacks by armor penetrating weapons, such as high-explosive, armor piercing (HEAT) rounds and armor piercing sabot rounds by detonating (creating a counter-blast) on impact prior to the weapon penetrating the tank’s turret or hull. This disrupts the weapon’s effects or destroys it outright, saving the tank’s crew and possibly the tank itself. In some applications, when fastened at a steep angle, they can also work to deflect the weapon’s effects.
It’s unclear if the Kontakt-1 bricks could make the cope cage more viable. While such a screen might better protect against light top-attacks from drone-dropped mortars or FPV kamikaze drones, those systems only posed serious threats to tanks with open hatches. Also they appear to be placed flat, meaning they lose the ability to help deflect weapon’s angle.
Whether they could help counter top-attack capable anti-tank missiles is another question entirely. Also, if someone was standing in the hatch below them when they detonated, what damage would be inflicted on them, if any, is another question.
The evolution and proliferation of these screens has been somewhat fascinating to watch over the last year and a half. Clearly, work is still ongoing into making them serve an intended purpose, at least in a more robust manner.
