Which statement about the three lines of effort is correct?

• A. Generating a force with a purpose; Sustained engagement; Executing operations across the spectrum of lethality
• B. Sustained engagement as a separate aim only
• C. Building bases and equipment
• D. Deterrence and partnerships

Answer: (A)

The main idea here is that these three lines of effort describe how the Army organizes its work to deter and win in complex environments by tackling three intertwined priorities. First, generating a force with a purpose means building readiness and alignment—making sure people, training, equipment, and doctrine are all focused on clear, mission-driven outcomes. Second, sustained engagement emphasizes ongoing presence and relationships—maintaining partnerships, legitimacy, and influence with partners and populations over time to prevent conflict and build resilience. Third, executing operations across the spectrum of lethality captures the ability to apply a full range of actions, from nonkinetic to kinetic, selecting the right level of force and effects to achieve objectives with proportionality and restraint.

This combination is why the statement is the best fit: it shows the complete set of concurrent priorities that guide how the force is prepared, how it builds and maintains partnerships, and how it conducts operations when required. The other descriptions focus on only one aspect or mischaracterize the scope by emphasizing bases and equipment or focusing solely on deterrence and partnerships, which don’t reflect the integrated three-line approach.
