Question then. When USMC Civil Affairs deploy, do they execute a CMO mission in accordance with JP 3-57? Going back to actual execution of Civil Affairs role in any theater doesn't typically fall under any service specific Command. SOCOM doesn't have OPCON/TACON Army Civil Affairs.
I'm not an expert but I believe that they do but they do so underneath the operational and tactical command of a Marine Corps unit, normally the MEF or MEB. Who owns Army Civil Affairs at home and in theater normally? They don't work for the TSOC?
