The type of mission rehearsal routinely performed by a subordinate leader after receiving instructions like an OPORD (Operations Order) or FRAGO (Fragmentary Order) is called a "Tactical Rehearsal."

The rehearsal helps to identify potential issues and enhances coordination, communication, and overall mission effectiveness.
