What is one method of identifying Soldiers with substance abuse problems?

Voluntary self-identification is a crucial method of identifying Soldiers with substance abuse problems because it encourages individuals to come forward without the fear of immediate punitive action. This approach fosters a supportive environment where Soldiers can seek help for their issues. By allowing individuals to acknowledge their struggles voluntarily, the Army can provide the necessary support resources, thus facilitating rehabilitation and promoting a healthier force overall. Such programs emphasize care and rehabilitation rather than punishment, aligning with the Army's values and commitment to the well-being of its personnel.

In contrast, the other options tend to focus on external pressure or assessments that may not create the same level of trust or openness among Soldiers regarding their substance use issues.
