I think CI shouldn't be beholden to FO's regulations regarding explosives, we are a hostile GOI fighting asymmetrical warfare against a larger force. Backblast and noise are also invalid for reasoning in my opinion, because gunfire indoors is super concussive regardless.
I'd suggest personally one of two things:
1. Remove the guideline on UBGLs for FO
2. If you are unwilling to remove it, amend it to allow explosives on GOI, even inside the site, usage still leaving the operator liable if there is collateral.
