For FAD IV (4), which option is the correct answer in the data?

• A. Active Army
• B. National Guard
• C. U.S. Army Reserve
• D. Air National Guard

Answer: (B)

Understanding the different components of the Army helps you pick the right option here. The Army National Guard is a state-based reserve component with a dual mission: it can be called up by a governor for state emergencies and by the president for federal service. This distinguishes it from the Active Army (full-time active duty), which is always under federal control and deployed for national missions, and from the U.S. Army Reserve (a federally run reserve force not tied to state control). It also differs from the Air National Guard, which is the air force reserve component, not part of the Army. So, for a data field that identifies the Army’s reserve component with that state-based, dual-role nature, the Army National Guard is the correct match.
