What does the term 'Required strength' refer to in the context of a unit?

The term 'Required strength' in the context of a unit refers specifically to the personnel authorized by the Modified Table of Organization and Equipment (MTOE) or Table of Distribution and Allowances (TDA). This definition is critical because it outlines the ideal or planned structure of the unit based on its mission, capabilities, and operational requirements.

MTOE and TDA documents provide guidance on how many personnel are needed to effectively fill the roles required for the unit to function optimally. Thus, 'Required strength' is not simply about counting those who are currently present or those who are ready to train; it encompasses a strategic overview of personnel requirements as determined by official organizational documents.
