This United States Marine Corps manual, Marine Corps Tactical Publication MCTP 3-30A Command and Staff Action July 2020, provides staff tactics, techniques, and procedures that support the commander's decision making process at all levels of command. The publication consists of two parts. Part I describes command and staff organizations and describes the MAGTF command structure to include the commander's personal, general, and special staffs. MCTP 3-30A describes billets within each functional organization as they relate to the commander and identifies these roles and responsibilities. Part II identifies key coordination measures or staff actions necessary to aid the commander in decision making and reinforces key means of communications via standardized reports and information management systems and processes. The appendices include several sample formats for correspondence and staff studies.
MCTP 3-30A informs Marines on the basic composition of MAGTF staffs and describes basic staff skills corresponding to effective action officers. As such, this publication will also include staff sections that emerged over the last decade such as the G-9. The information contained in MCTP 3-30A applies to major subordinate commands, regiment/group, and battalion/squadron levels. Any Marine at any echelon can reference this publication to understand basic command and staff actions.
