National flaps are different from regular lodge flaps in that they are worn by arrowmen from lodges all across the country. Issued by the National Executive Secretary of the National Committee of the Order of the Arrow, these flaps are only worn by an individual while serving in the capacity indicated by the flap and have traditionally been restricted to two per person. National flaps have been issued for members of the National Committee, and the OA Service Corps for the 1977, 1981, 1985, 1989, 1993, 1997, and 2001 National Jamborees.

At the 1993 National Jamboree, I was in Staff Troop #3260 of the OA Service Corps. We were broken down into four troops, plus support staff and key members of the National Committee. It's my guess that there were only 125 of us total, not including Youth Services staff.

I am very proud to have served on the OA Service Corps for the 1993 National Jamboree. We were housed at Longstreet Camp, Youth Services HQ near the OA Indian Village and Trading Post C. We got to work with a lot of cool people, including Del Loder, Brian Beaverstock, Ed Pease, Allen Mossman, and Dr. Carl Marchetti. While the weather was not as cooperative as it should have been, we all had a really memorable time.
