Just because some Marine who might have reenlisted into the Army and somehow ended up in CAG doesn't count as the Marine Corps contribution to JSOC.
I'm confused on what you are trying to say Teufel.
The Army, Air Force, and Navy all have whole units who are part of JSOC, all I am trying to say is what is to keep the USMC from creating a Tier 1 CT unit as well? I don't think that sounds too unreasonable.
I sent you a PM. I am not going to get too much into it on an online forum but just suffice it to say that JSOC is a joint organization that has representation from all the services.
