In the 1/3 - 2/3 rule, what should 2/3 of the time be spent on?

The 1/3 - 2/3 rule is an essential guideline in military planning that emphasizes effective time management during operations. Under this rule, it's recommended that 2/3 of the available time be allocated to rehearsals.

Rehearsals are critical for ensuring that all team members are familiar with their roles, understand the mission objectives, and can execute their tasks effectively. This practice helps identify potential issues in the execution phase and allows for adjustments before the actual operation. By dedicating the majority of the time to rehearsals, units can reinforce their plans, build confidence, and synchronize their efforts, ultimately leading to a smoother and more successful operation.

While the other options, such as the mission itself, travel, and preparation of reports, are important components of military operations, the focus on rehearsals aligns with the need for comprehensive preparation and teamwork, which is vital for achieving mission success.
