This Handbook reflects and supports doctrine in Marine Corps Doctrinal Publication (MCDP) 4, Logistics; Marine Corps Warfighting Publication (MCWP) 3-40, Logistics Operations; Marine Corps Tactical Publication (MCTP) 3-40B, Tactical Level Logistics; MCTP 3-40C, Operational Level Logistics; and MCTP 3-40H, MAGTF Supply Operations. However, it provides some unique tactics, techniques, and procedures specific to the audience of this Handbook that are not covered by doctrine. MARFOR G-4s, working with deployed Marine forces, will make decisions that best support forces in the GCC AORs.
