What shoulder patch will be worn on the Army Service Uniform (ASU)?

In the Army Service Uniform (ASU), the correct practice is to not wear any shoulder patch, except in certain specific cases, such as when authorized for specific missions or during combat operations. Typically, service members do not display a unit patch on their ASU to maintain the uniformity and formal appearance associated with the ASU. The absence of a shoulder patch reflects the formal nature of the uniform, distinguishing it from other types of uniforms that may have different insignia representing the wearer's unit.

While other options mention different kinds of patches, they do not apply to the standard practice for the ASU in most situations, which emphasizes a clean and refined appearance, not cluttered by additional insignia.
