How is the U.S. insignia disk worn on the female Army Blue Service uniform?

The U.S. insignia disk is worn on the female Army Blue Service uniform centered on the right collar. This placement is significant as it adheres to Army regulations, which dictate the specific positioning of insignia for uniformity and to denote rank and affiliation properly. By placing the insignia disk on the right collar, it aligns with the uniform standards ensuring that all soldiers present a cohesive and disciplined appearance.

The other options do not align with official guidelines, which specify that insignia must be placed in designated locations to maintain a consistent and professional look across the board for all service members. Each insignia, like the one on the collar, has its rightful place that is recognized universally within the Army, promoting a sense of camaraderie and identity.
