    they’re trying to detonate incoming shaped charges early to prevent the formation of the jet of hot metal that sprays into the tank. these kinds of munitions work best on contact with the turret or hull - their explosive creates spalling, which is pretty much liquid metal fragments that bounce around the crew cabin, perforating mobliks and cooking off the ammunition.

      I think maybe you’re confusing two different things?

      HEAT is a shaped charge that explodes and compresses a thin layer of metal (usually copper I think) into a tiny superheated lance that is extremely good at piercing armor. There’s no spalling involved afaik.

      HESH creates spalling by basically being a big explosive that moulds to the armor before exploding, and uses a quirk of how the force moves through the armor to make the armor on the inside break off and bounce around the tank- that’s spall.

      I’m pretty sure just using bricks like this would be effective against both types of ammo, though.

      Maybe I’m entirely wrong idk I’m just a nerd on the internet.
