S-4 is responsible for which area?

• A. Intelligence
• B. Logistics
• C. Signal/communications
• D. Civil affairs

Answer: (B)

This item tests understanding of staff roles within a military organization, specifically which function the S-4 handles. The S-4 is responsible for logistics, meaning planning and executing the unit’s supply, maintenance, transportation, and general materiel readiness. They ensure the unit has the right equipment, parts, fuel, rations, and services needed to operate, and they coordinate how those resources are distributed and moved.

Intelligence is managed by the S-2, focusing on information gathering and analysis. Signal/communications falls under the S-6 (or a similar communications role), handling radios, networks, and communications security. Civil affairs are overseen by the S-5, dealing with civilian interactions and civil-military operations. Because of these distinct focuses, logistics is the correct area for S-4.
