Yeah. Russian vehicles with cages or sheds sometimes take several hits to cook off. I assume soldiers wouldn’t post many videos of failed strikes so it’s hard to know exactly how effective they are overall, but detonating an explosive away from the vehicle’s armor is broadly very good.

I’ve read that a shaped charge’s armor piercing jet of plasma has a fairly long reach. A direct hit with the plasma spear directed toward the center of the vehicle would probably still pierce the vehicle. However, a cage like that might provide protection from a glancing blow, where the plasma jet is not directed toward the center of mass - like, instead of getting a hole through the corner of the roof, the jet misses entirely.

It works against the shit Russia uses
