    I was thinking more of the tried and true soviet RKG3 and the half dozen variants/clones. They’re terrifying when they work, but everyone figured out that cope cages and improvised shields create such a gap that renders them mostly useless, and at the end of the day it’s playing lawn darts with a tank. For some reason they’re still all over the place, probably used more for IEDs or destroying infrastructure than tanks

      Not sure how much I really want to commit to that air gap idea. Pretty much every time there is data, the ideal standoff is somewhere between 8 and 12 times the diameter for a given HEAT warhead.

      The nets and cages seen like on US vehicles weren’t designed to give standoff on an ideal detonation, but to catch the nose of an incoming round in the open space and hopefully strip apart or dud it. It is commonly called “statistical armor” because it relies on the statistical chance of being hit in the right place to work.

      MPDI link article with charts and more explanation.

      Against a weapon which won’t be shorted out by this armor it is, well, cope. The reason you don’t see RKG-3s often in Ukraine footage is more likely they they aren’t common, and other better options that can be fired accurately and from more distance are.
