Final answer:
AR 600-9 sets the Body Composition Program standards for active and reserve soldiers in the U.S. Army, and requires them to maintain physical fitness and readiness through proper weight control measures.
Step-by-step explanation:
AR 600-9 refers to the Army Regulation that sets the Body Composition Program for the United States Army, often known as the Army's Weight Control Program. This regulation establishes the policy for the assessment of body composition and the administrative process for soldiers who may not meet the required standards. The purpose of AR 600-9 is to ensure that all soldiers achieve and maintain optimal well-being and performance under all conditions. The standards set forth in this regulation apply to all enlisted soldiers, warrant officers, and commissioned officers in the active Army, the Army National Guard/Army National Guard of the United States, and the U.S. Army Reserve. However, there are different procedural guidelines for the Reserve and National Guard components, as their service members do not perform duty on a full-time basis.
Meeting the physical fitness standards, including weight control, is crucial for soldiers to perform their duties effectively. Failure to meet these standards may result in administrative actions, including possible separation from service. It is imperative for military personnel to maintain physical readiness through a proper diet and exercise program, to fulfill the mission requirements of the United States Army.
