How must mustaches be maintained?

Maintaining mustaches according to military standards typically requires them to be kept neatly trimmed, tapered, and tidy. This standard ensures a professional appearance that aligns with the military's emphasis on uniformity and discipline. A properly maintained mustache should not extend beyond the corners of the mouth and must be groomed in a way that reflects respect for the uniform and the service. This implies regular upkeep to avoid any unsightly or unkempt looks that could detract from a soldier’s overall appearance.

In contrast, having thick and bushy mustaches, chopping them off entirely, or letting them grow stylishly long would not adhere to the military's grooming standards. Each of these alternatives could lead to an appearance that fails to project the discipline and neatness that is expected from personnel in the armed forces.
