Final answer:
An accurate answer regarding the number of members required for a full-time DAPA assignment within military commands cannot be provided without further context or clarification on the acronym 'DAPA'.
The International Association of Counseling Services staffing recommendations for counseling services is not applicable to Department of Defense directives.
Step-by-step explanation:
The question appears to be related to the Department of Defense Directive 1304.26, which may outline personnel assignments within military commands. However, without the specific context of the directive or an understanding of the acronym 'DAPA' in this context, it is not possible to provide an accurate number of members required for a full-time DAPA assignment. The term 'DAPA' is often associated with Navy Drug and Alcohol Program Advisors, but the question does not clarify if this is the intended reference.
Additionally, the information from the International Association of Counseling Services regarding staff-to-student ratios is not directly relevant to Department of Defense staffing requirements. Such ratios are typically specific to educational or counseling services, rather than military personnel assignments.
