Which Army Regulation governs uniform and appearance standards?

The regulation that governs uniform and appearance standards in the Army is AR 670-1. This regulation outlines policies, standards, and procedures for wearing and maintaining the Army uniform, including specifics on grooming, insignia placement, and overall appearance. It ensures soldiers present a professional image, which is essential for maintaining discipline and military traditions.

AR 670-1 is crucial as it defines what constitutes proper uniform wear, addressing both the mandatory items and those that may be optional, as well as standards of fitness and grooming that contribute to unit cohesion and morale. It serves as a guide to ensure that soldiers portray the values and professionalism of the Army through their appearance.

The other options refer to different aspects of Army regulations: AR-600-85 deals with substance abuse prevention and control, AR-600-9 covers the Army Weight Control Program, and AR-600-20 pertains to command policy, which includes aspects of harassment and discrimination. While all these regulations are important in their respective contexts, they do not specifically address uniform and appearance standards.
