How many Combat Sustainment Support Battalions (CSSBs) can be attached to a sustainment brigade?

The correct answer is based on the organizational structure of sustainment brigades within the U.S. Army. Sustainment brigades are specifically designed to provide logistical support to units during large-scale combat operations. Each sustainment brigade can be augmented with Combat Sustainment Support Battalions (CSSBs) to boost its capacity for supply chain management, maintenance, transportation, and distribution of essential supplies.

The figure of six CSSBs aligns with the Army's organizational doctrine and provides an optimal balance for effective support across various operational environments. This number allows sustainment brigades to maintain operational flexibility and responsiveness, catering to the needs of multiple maneuver units simultaneously without overextending their logistical capabilities.

Understanding this organizational structure is crucial for effectively planning and executing operations where sustainment is vital for maintaining combat effectiveness. The other options present numbers that exceed the established doctrine, emphasizing the importance of having a clear grasp of the structure and limitations within military logistics.
