Midshipmen at the US Naval Academy, US Merchant Marine Academy, and in the NROTC wear uniforms that comply with standards established for commissioned officers of the Navy, with shoulder board and sleeve insignia varying by school year or midshipman officer rank as prescribed by Chapter 6 of Navy Uniform Regulations. Midshipmen wear gold fouled anchors as the primary insignia on caps and shoulder boards and gold plain anchors as collar insignia on service dress and full dress uniforms. Marine-option midshipmen in the NROTC wear gold Eagle, Globe and Anchor insignia in place of the fouled anchor insignia worn by all other midshipmen.
