What authority do commanders have regarding substance abuse within their units?

Commanders are given the authority to enforce drug policy, initiate testing, and address substance abuse issues within their units. This responsibility is crucial for maintaining the readiness and discipline of the military. By being able to enforce policies, commanders can ensure compliance with regulations that are designed to prevent substance abuse and mitigate its impacts on operational effectiveness.

Furthermore, initiation of testing allows commanders to identify and manage potential substance abuse problems proactively. Addressing substance abuse issues directly falls under the commander’s purview as they work to maintain a healthy and mission-ready force. This authority enables commanders to take necessary actions to support soldiers who may be struggling with substance abuse and to implement intervention strategies effectively.

The other options do not fully encapsulate the comprehensive role that commanders play in managing substance abuse in the military context. Only option B accurately reflects the scope and depth of a commander's responsibilities concerning substance abuse within their units.
