Which rehersal is used to determine how a surbordinate leader intend to accomplish the mission?

The rehearsal used to determine how a subordinate leader intends to accomplish the mission is typically called a "backbrief." During a backbrief, the subordinate leader presents their plan to the senior leader, outlining their understanding of the mission, the approach they intend to take, and how they will execute it. This allows for clarification, feedback, and alignment on objectives, ensuring everyone is on the same page before execution.
