What regulation governs the wear and appearance of military uniforms?

The wear and appearance of military uniforms are governed by AR 670-1. This regulation provides detailed guidelines on how soldiers should wear their uniforms, including specifications on authorized uniforms, insignia, and the overall appearance. It establishes standards to ensure that soldiers' attire is professional and represents the U.S. Army appropriately. Adherence to these guidelines is crucial for maintaining discipline and uniformity within the ranks, reflecting the values and traditions of the Army.

The other regulations listed pertain to different areas: AR 600-20 focuses on Army command policy, AR 670-2 is a previous version of uniform regulations that has been superseded by AR 670-1, and AR 700-8 deals with supply policy. Thus, AR 670-1 is the primary regulation specifically addressing the wear and appearance of military uniforms.
