Ah, ok. I read the "Equipment Deployed" section which called out gelatin, body armor etc. but not walls and such. Ctrl-F'ed for "drywall" just to be sure and didn't hit since the term isn't in the document (though obviously they mention walls lots of times which I failed to notice).

I still say though, the original comment I replied to is mischaracterizing what happens when 5.56 hits drywall. It does not make a huge hole, and I don't know how you could say it "would not significantly harm" a person on the other side. See some tests here w/ photos regarding drywall and 5.56 penetration: https://www.theboxotruth.com/the-box-o-truth-14-rifles-shotg...

Pistol calibers very well may penetrate further after passing through drywall (as the FBI tests indicate) but there is no evidence to claim that 5.56 is less than lethal after passing through a sheet of drywall.
