What term describes a Soldier volunteering to provide a sample without being ordered?

The term that captures the essence of a Soldier voluntarily providing a sample without being ordered is "Consent (VO)." This phrase highlights the idea that the Soldier has given their agreement to participate in testing, emphasizing the voluntary aspect of the action. It's important to understand that 'consent' implies the individual is aware of and agrees to what they are doing without coercion, which is a critical concept in the context of drug testing and accountability in the Army.

While the other options touch on related aspects, they don't encapsulate the specific combination of voluntary action and agreement linked to the context of voluntarily providing a sample as well as "Consent (VO)" does. For instance, informed consent generally pertains to an understanding of a procedure or test but does not necessarily denote the voluntary nature directly tied to the action of providing a sample. Voluntary Offering could imply a similar action but may lack the formal terminology used in the regulations. Self-Initiated Sample suggests the act has been taken on one's own accord, yet does not explicitly connect to the formal acknowledgment and agreement found in "Consent (VO)," which is a key aspect of the procedure in question.
