Correct. You're also allowed by CO law to use force up to and including deadly force in defense of a third person, but only if there aren't any walls, fences, doors, etc. in between you and that third person. Because then you would practicing self offense, not self defense, and that, as we all now know, is illegal.

Girlscouts? Hmmm, I don't know... I think it's kinda dangerous to teach young girls self esteem and leadership skills.
Subpart 3 is not a restriction on what kind of training you can have. Its an explicit carve out from the acts forbidden in (1) and (2).
Those requirements do not appear in CRS.Addition: you need some government sponsored authority to attend this training ie...you have to have a need for it. Everyday CCW'er doesn't need to know door breaching techniques, cops = yes. There is a reason I have to have to be vetted to attend the training I do. No grandmas with a snub nose .38 there and also no haji's wanting to use that knowledge against us.
I've illustrated what Colorado statutes say. One could go to the other state laws that cover this subject. You are going to find that most of them will include the intent to commit a crime element because First Amendment protections of speech will protect anyone who wishes to "teach" tactics of any kind.
That the reputable shooting schools do not teach SWAT or counter-terror dynamic entry and other such tactics to civilians is of course their choice, their ethics, and obviously a poor business practice, and I'm not commenting upon that. The assertion that it would be, without qualification, illegal for them to do so is one that I'd say is untrue.
Now obviously, if one found a school that purported to teach such to civilians ... well, I'm pretty sure that in no time at all, you would be straddling a speed bag and beating it to death with a loaded gun, craning your neck in some weird 270 degree scanning motion and other silly things....
