In its redesign, the Army transitioned from being ____________-centric to a ____________-centric modular combat team.

The transition described in the question refers to the Army's shift in its organizational structure, which emphasizes greater flexibility and responsiveness in combat operations. The correct answer indicates that the focus moved from a division-centric model to a brigade-centric modular combat team.

This transformation is significant because brigade combat teams (BCTs) are more adaptable and can be rapidly deployed in response to various operational needs. The modular structure allows for the integration of different types of units that can be tailored to specific missions, providing commanders with a versatile fighting force capable of responding effectively to diverse threats.

Brigade-level formations can operate independently and with a greater degree of self-sufficiency compared to larger divisions, which often require more extensive logistical support and coordination. This shift aligns with modern warfare's increasing demand for speed, adaptability, and the ability to conduct operations at various levels of conflict.

By understanding this transition, military personnel can better appreciate the implications of modularity and how it enhances the capabilities of the Army in contemporary combat scenarios.
