Which sequence correctly lists the major planning elements in OSMEAC?

• A. Orientation, Situation, Mission, Execution, Admin and Logistics, Command and Signal
• B. Orientation, Situation, Mission, Endstate, Admin and Logistics, Command and Signal
• C. Situation, Orientation, Mission, Execution, Admin and Logistics, Command and Signal
• D. Orientation, Situation, Mission, Execution, Endstate, Command and Signal

Answer: (A)

The sequence tested is the standard order used to structure a Marine planning approach: Orientation sets the context, Situation assesses the current conditions and constraints, Mission states the unit’s purpose, Execution outlines how the mission will be carried out, Admin and Logistics covers the sustainment and support needed, and Command and Signal defines the leadership, lines of authority, and communications. This progression moves from establishing the frame (Orientation) to understanding the environment (Situation), then defining what must be done (Mission), describing how it will be done (Execution), ensuring support (Admin and Logistics), and finally detailing how command and control will operate (Command and Signal). The other options introduce Endstate or misorder elements, which do not align with the established OSMEAC structure.
