Which of the following is NOT one of the Army values?

The correct answer is that 'Service' is NOT one of the Army values. The Army Values are a set of guiding principles that shape the character and actions of Army Soldiers. These values include Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage. While 'Service' encompasses the notion of putting the needs of the Army and the country above one's own, it is specifically represented in the values through 'Selfless Service.' Therefore, 'Service' as a standalone value is not officially recognized among the distinct Army Values, which is why it is the correct answer for this question. Understanding these principles is key to embodying the ethos of an Army professional.
