Logistics Phase Captains Career Course (CCC) 2026 – Comprehensive All-in-One Sustainment Practice Test for Optimal Preparation

The battalion S4 is the logistics officer on the battalion staff, responsible for planning and executing sustainment—supply, maintenance, transportation, and services—to keep the unit able to move and fight. Their focus is to enable the battalion to maneuver by ensuring the right support is available at the right time and place, coordinating with the Brigade Support Battalion and Forward Support Company as needed. The other roles listed are distinct positions (an S3 in a different unit, and the commanders of a support company or battalion) and aren’t what defines the battalion S4. Since the S4’s job is to enable movement and combat operations through logistics, the function they most directly support is Maneuver.
