After how much time can a commander send a soldier who hasn't tested to medical?

The correct answer is based on the guidelines provided in the Army Substance Abuse Program, which stipulates that a commander must manage the situation of a soldier who has not been tested for substance abuse in a reasonable manner. More specifically, the commander is allowed to send a soldier to medical evaluation following a delay that is longer than 3 hours from the time they were supposed to test.

This time frame is designed to ensure that the soldier is still available for testing and is not unduly delayed, while also taking into account the practicalities of managing personnel and resources. By waiting beyond 3 hours, the commander is adhering to regulations, which can help in maintaining the integrity of the testing process and ensuring proper tracking of the soldier's availability. This balance is key in upholding the objectives of the Army Substance Abuse Program, which include ensuring readiness and accountability among soldiers.
