What is the proper way to wear a flag patch on one's shoulder sleeve?
To wear our country's flag properly, the field of stars should be worn closest to your heart. Thus, if your patch is to be worn on your LEFT sleeve, use a left flag. For patches worn on your RIGHT sleeve, use a "right" or "reversed field" flag. Since the law does not specifically address the positioning of the patch, a decision is left to the discretion of the organization prescribing the wear. Some elect to use the "left" flag on both sleeves. [Note: many states and cities have ordinances pertaining to the use of the flag; you may wish to contact the Attorney General of your state or the City Attorney’s office regarding this matter.] If you are planning to wear only one patch, it is recommended that you wear a "left" flag on your left sleeve. Military guidelines specify that in support of joint or multi-national operations, the "right" flag is worn on the right sleeve, 1/4" below the shoulder seam or 1/8" below any required unit patches.
