>cope cage>slat armor>drone netAll distinct forms of ad hoc armor against different threats. Slat armor has been used for decades and is useful against simple warheads without tandem charges. Drone nets are older than the Ukraine war and limit the impact of dropped munitions and FPVs.
Cope cages were raised platforms of metal bars intended to stop a warhead coming from above. They were overbuilt for grenades, underbuilt for Javelins, and did not make it deep enough into Ukraine to see RPG attacks from above in urban warfare. Thus, they were pointless and were phased out in favor of canopies better suited for drone protection.
Armor that doesn't serve its intended use, like sand bags or spare tracks in WW2, function more as emotional support than anything else.
