Arm Patch Protocols
"No part of the flag should ever be used as a costume or athletic uniform. However, a flag patch may be affixed to the uniform of military personnel, firemen, policemen, and members of patriotic organizations. The flag represents a living country and is itself considered a living thing. Therefore, the lapel flag pin being a replica, should be worn on the left lapel near the heart."
The National Flag Foundation suggests "...we recommend that the flag patch on the left sleeve of a uniform should have the union to the viewer's left while a patch on the right sleeve should be displayed with the union to the viewer's right so that, in both cases, the flag is facing forward and is streaming to the back as the person moves forward."
