Which statement best describes the definition of command?

• A. A commissioned or Warrant Officer by virtue of grade and assignment exercises primary command authority
• B. They must be the oldest officer
• C. They must have civilian approval
• D. They must be designated by the Secretary of Defense

Answer: (A)

Command is the authority a person in a leadership position has to direct subordinates and accomplish assigned missions. This authority isn’t earned by age, civilian permission, or a blanket designation from a top civilian office; it comes from the officer’s rank (grade) and the specific command position they hold.

That’s why the statement describing command as being exercised by a commissioned or Warrant Officer by virtue of grade and assignment is the best fit. It captures that command authority is tied to the role and the position, not to being the oldest, nor to civilian approval, nor to a designation by the Secretary of Defense.
