For the record and those just entering the service, I would like to clarify that CNO is not a "logistician" per se. Under Goldwater-Nichols, service chiefs sit as members of the Joint Chiefs of Staff, which as thread first intimated, is not part of Chain of Command. Combatant Commanders are the Joint warfighters and service chiefs "train, equip and provide" forces for them to use as set forth in Title 10 of the US Code. Logistics is a particular domain and subset of those responsibilities and also part and parcel of TRANSCOM, one of the "supporting" Combatant Commanders.
