What is the main goal of a Combined Arms rehearsal?

The main goal of a Combined Arms rehearsal is to ensure synchronization of plans between subordinate units. This rehearsal is a critical component of the planning process, as it allows various units involved in an operation to share their plans, clarify their roles, and confirm that their actions will complement one another on the battlefield. By synchronizing their operations, units can eliminate gaps in their strategies and ensure that they work cohesively towards unified objectives. This coordination is vital in combined arms operations, where different types of forces (infantry, armor, artillery, etc.) must operate in harmony to achieve mission success.

The other choices relate to different operational aspects but do not capture the primary focus of a Combined Arms rehearsal. Developing a new operational plan emphasizes planning rather than synchronization, conducting a training exercise for higher command does not reflect the rehearsal’s specific function, and assessing the readiness of units, while important, is more about evaluating capabilities than ensuring collaborative execution of planned operations. The rehearsal is firmly rooted in alignment and integration, which is why the selected answer accurately reflects the primary objective.
