I pointed to the wrong section. Will post and edit in a few.

20–23. Overcoat, ceremonial, blue a. Type. The ceremonial blue overcoat (CBO) is an optional purchase item authorized for male or female general officers. Their aides-de-camp, their CSM, and their enlisted aides are authorized to wear the CBO with the white scarf. (1) Uponreassignment,thegeneralofficerandtheirCSMorsergeantmajorwillretaintheovercoat.TheCBOwill be turned in upon expiration term of service. (2) The aides-de-camp and the enlisted aides must turn their CBO into the central issuing facility upon reassign- ment. b. Description. The material is polyester, wool, or a similar type of woven fabric. A white scarf is also authorized. c. How worn. The CBO with the white scarf is worn on formal ceremonial occasions. The CBO is appropriate for wear when cold weather conditions would reasonably preclude the wear of the ASU coat alone. It is recognized that certain ceremonies, which may take place during periods of cold weather, demand a level of formality and solemnity that cannot be achieved by wearing the standard black all-weather coat. Shoulder straps (shoulder boards with ranks) will be worn on all the CBO for general officers. The ASU coat will not be worn under the CBO. The CBO will have rear pleats and should be worn with the white scarf.
