The Marine Corps Combat Development Command (MCCDC) has responsibility for United States Marine Corps doctrine. The capstone doctrinal document is Warfighting (MCDP1), along with MCDP's 1-1, 1–2, and 1–3 (Strategy, Campaigning, and Tactics, respectively). MCDP 1-0 (Marine Corps Operations) translates the philosophical-based capstone/keystone publications into operational doctrine.
