Red is the outer composite, green is the integrated spall liner, yellow is the innermost plate (which is basically just used to weld things to it):
It would potentially create more spall within the armor array itself, but most of the fragments of the armor broken off in the armor array would just get stuck inside the armor array (and never get into the crew compartment or go very far from their original position in the array).
The bits that get pulled along are in the accompanying image to that one, where the green parts at the top and bottom get tugged along even though they aren’t directly hit by the penetrator.
The thing is, in that array would the Yellow area would represent the backplate?, if so i dont see how the Integrated spall liner would have affect in game, as the penetration is calculated just by the last plate already, so it wouldnt really be able to “absorbe” any shock that is generated in that plate itself.
The absorption IRL would have the effect of lessening the amount of spall generated, and in game this could be implemented by lowering the number of spall fragments generated and lowering the angle of the spall cone (maybe not as much as the curtain liners, since there isn’t anything I could find on the comparative effectiveness of the Abrams’ specific liner to the traditional style, but a lowering in general would be accurate).
