What fraction of the Army constitutes the Operational Force?

• A. 1/3 of the Army
• B. 2/3 of the Army
• C. 1/2 of the Army
• D. 3/4 of the Army

Answer: (B)

The key idea is that the Operational Force consists of the units that are ready and capable of deploying to fight, while the rest of the Army is devoted to generating and sustaining that force through training, maintenance, and support. In common Army structure, about two-thirds of the total force falls into the Operational Force, with roughly one-third making up the generating and institutional forces that train, equip, and sustain those deployable units. So the fraction that constitutes the Operational Force is two-thirds. The other fractions don’t align with this established balance between deployable units and the forces that generate and support them.
