Russian Tank With ‘Cope Cage’ Covered In Explosive Reactive Armor Emerges

MAY 6, 2023 

A 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. 

Cope cages began appearing on Russian armored vehicles in late 2021 amid the pre-war buildup as a counter to loitering munitions and drones, particularly the Turkish-made TB-2 used in the 2020 Nagorno-Karabakh War and later by Ukraine against Russian forces. It seemed there was also hope, albeit misguided, that they could defeat anti-armor guided missiles capable of top-attacks, as well.

As the war progressed, cope cages found their way to TOS-1 thermobaric rocket launchers and Soviet-era T-62s pressed into service after heavy losses. Russian rear-area troops soon adopted similar improvised, “Mad Max” armor in the face of attacks by Ukrainian troops behind the lines. 

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.


  1. This is yet another desperate method to try and protect their tanks. I was wondering if and when the orcs would try this.
    To use explosive reactive armor, the tank must have adequately thick armor to protects its crew from the blast. The top of any tank is only thinly armored, and so this measure could still kill a tank, even if by its own reactive armor blast. Reactive armor is dangerous to any friendly infantry nearby, and I think placing it on a position that spreads the blast wave and fragments in a near 360-degree circle is even more dangerous. And, as the article stated, this is even worse if a hatch is open. And, this cope cage reactive armor covers only a fairly small portion of the tank. Javelins and other top attack weapons don’t only hit the turret.
    I think it’s safe to assume that we will see these contraptions to disappear again soon.

  2. How is this going to stop a DU round that will slice through the tank like a hot knife through butter? Also the Javelin has a mechanism that destroys the reactive armour before the main expolsion.

    • ERA can help with a sabot round, at best. I doubt it will keep the depleted U penetrator from making it through, though. I have doubts about it stopping the top attack missiles as I think they have two stage warheads, IIRC.
