Under which condition may commanders direct drug testing?

Commanders are permitted to direct drug testing during unit inspections as they are tasked with maintaining the readiness and discipline of their units. Unit inspections often occur to ensure adherence to policies, regulations, and overall operational readiness, and drug testing serves as a tool to uphold standards of conduct and ensure the well-being of the personnel.

Routine training exercises, annual performance reviews, and team-building events generally do not carry the same imperative for drug testing, as these activities may focus more on performance assessment, morale, and team cohesion rather than compliance with the legal and health standards that drug testing ensures. Thus, unit inspections stand out as the appropriate condition for commanders to implement drug testing.
