During landings and airborne operations, assault troops and paratroops were often issued US flags to wear on their upper arms to help avoid "friendly fire" incidents. Most were discarded by the troops within days (or hours) as they a bit of a detriment to concealment. These are most often associated with airborne and glider units, but their issue was not exclusive to those troops. The flags were sewn to the upper right arm of the uniform. The edge has extra material to allow you to fold it over- but many troop simply tacked them on raw-edged.

Our 48-star flags are high quality from an authenticity standpoint- like originals, are not very resilient- they were only meant to last a few days.
