AR670-1
20–12. Badges authorized for wear on Army uniforms
A badge is awarded to an individual for identification purposes or for attaining a special skill or proficiency. The criteria for the award of Army badges are contained in AR 600–8–22 and in NGR 601–1 for ARNG recruiting and retention identification badges. Most combat and special skill badges are available in full and dress miniature sizes. The combat infantryman and expert infantryman badges are the only badges available in three sizes (full- sized, miniature, and dress miniature). The following badges are authorized for wear on the Army uniform:
a. Military badges awarded by the U.S. Army, U.S. Air Force, U.S. Navy, U.S. Coast Guard, and the Director of Civil- ian Marksmanship.
b. Badges awarded by the Regular Army and Navy Union, and by the Army and Navy Union of the United States.
c. Marksmanship badges pertaining to national matches and approved by HQDA. Marksmanship badges from other U.S. Services are not authorized for wear on the Army uniform.

It goes on to specify further:
g. Inaccordance with AR600–8-22, personnelmustobtainwrittenauthorityfromArmyHumanResourcesCommand, Awards and Decorations Branch, before wearing badges on the uniform that were awarded by other U.S. Services or by the Director of Civilian Marksmanship. The following rules apply when wearing badges from other U.S. Services:
(1) Military combat or special skill badges awarded by other U.S. Services that are similar to U.S. Army combat or special skill badges are worn on the Army uniform in the same manner as U.S. Army combat or special skill badges, only if no Army badges are authorized for wear in the same group. For example, a Soldier who had no group 3 badges (as outlined in DA Pam 670–1) could wear aviation badges awarded by the U.S. Air Force as group 3 badges (as Army aviation and aviator badges are worn). However, if the individual was authorized to wear an Army badge in group 3, the Soldier would not be authorized to wear the group 3 badge from the U.S. Air Force.
(2) Skill badges awarded by other U.S. Services that are not similar to Army skill badges are worn as group 4 badges.
(3) Badges from other U.S. Services that indicate career fields are not authorized for wear (such as U.S. Air Force medical insignia or badges used to identify the duty, function, or classification of the wearer). Some examples are U.S. Air Force fire protection, air training command instructor, security police, or Naval Qualification Badges such as the Na- val aviation warfare specialist.
(4) Personnel will not wear badges awarded by other U.S. Services that, because of size or configuration, cannot be worn as group 4 badges. Subdued embroidered or metal skill badges authorized for wear by another U.S. Service, and authorized for wear on the Army uniform, may be worn on utility uniforms in the same manner as prescribed for Army badges.
