Which statement best describes DO in Be-Know-Do?

• A. Define the standards of discipline.
• B. Review past performance.
• C. Apply what you know, act, and do what you must.
• D. Plan the next operation exclusively.

Answer: (C)

In Be-Know-Do, the Do part is about turning knowledge into action—getting out there and applying what you’ve learned, taking initiative, and carrying out the required tasks. The statement that you apply what you know, act, and do what you must perfectly captures that execution mindset. It emphasizes performing under real conditions, not just thinking or planning.

Defining the standards of discipline focuses on character and behavior, which aligns more with Be. Reviewing past performance is about assessment and reflection, which isn’t the doing phase. Planning the next operation is about preparation and thinking ahead, which belongs to the knowing/planning aspect rather than taking action. So the action-focused description is the best fit for Do.
