Who is the target for random urinalysis testing conducted by the Marine Corps?

The correct answer identifies that all Marines are subject to random urinalysis testing. This policy is in place to uphold the standards of discipline, health, and readiness within the Marine Corps. Random testing serves as a deterrent against substance abuse and ensures compliance with regulations regarding drug use.

The inclusivity of the testing policy is crucial, as it emphasizes the accountability of every Marine, regardless of rank or position. This approach fosters a culture of professionalism and responsibility throughout the Corps. By subjecting all personnel to the same standards, the Marine Corps reinforces its commitment to maintaining operational readiness and integrity.

The other options exclude certain groups, which would undermine the overall effectiveness of the random urinalysis program as a means of monitoring and promoting a drug-free environment within the Marine Corps.
