Which item is a key input at Step 1: Receipt of the Mission?

• A. HHQ Plan/Order
• B. IPB
• C. War-game results
• D. Initial allocation of time

Answer: (A)

At the moment you receive the mission, the most important input guiding your next steps is the Higher Headquarters Plan/Order. This directive provides the mission statement, intent, constraints, and initial tasking from the senior level, and it sets the scope and boundaries for all planning that follows. Without that order, you wouldn’t know what needs to be accomplished or how success is defined, so it serves as the essential starting point for shaping your analysis and subsequent courses of action.

IPB is used during mission analysis to understand the environment and enemy considerations, not the trigger for starting planning. War-game results come after you’ve developed and evaluated potential courses of action, so they’re outputs of later steps. Initial allocation of time is a scheduling concern that follows from the mission and plan, not the primary input that initiates the process.
