Is paramilitary training illegal?

[Bailey Guns]

I know there is a mention of paramilitary training being illegal in CRS.

Yeah? Where?

As far as teaching "military training.." I don't know if it is listed in CFR. That is a VERY grey area that is controlled by DDTC and ITAR issues (if working with foreigners), none of which give slaps on the wrist. Most instructors will NOT teach "military technology" ie room entry, team tactics, breaching to civilians for this reason. If you do see someone teaching this stuff, they usually don't know what they are doing, hence the great amount youtube videos of idiots doing this stuff and almost killing themselves....if only darwin would step in at those moments.

I got news for ya. The .mil doesn't have the market cornered on "room entry, team tactics, breaching". That's standard SWAT or even active shooter stuff that most street officers learn and can be found being taught at many civilian shooting schools in the country. Ever go to Thunder Ranch?

There are lots of LE or former LE guys teaching this that would disagree with your assertion that "they usually don't know what they're doing".

We've been down this road before.
