Earlier in the war Russians welded similar structures, mostly on top like a roof, as a counter measure against javelin and other conventional anti-armour missiles, which is entirely ineffective. However, as the war progressed to rely on FPV drones carrying relatively less explosives, and the structures covering a lot more of the body of the vehicles, it gives the vehicles a fighting chance. Still not effective against conventional weapons though.
I think the goal with the Javelins was to try to fool the sensor making it think that the vehicle was taller than it is, causing the missile to fly too high, in top-down attack mode.
