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, 2001, 2005, 2010, 2013, 2017, and 2023 National Jamborees (Miura). Matching armbands were also issued for the 1989, 1993, 2005, 2010, and 2017 National Jamborees.
The OA has provided service troops since the 1950 National Jamboree. These early troops were issued armbands instead of flaps at the 1950, 1953, 1957, 1960, 1964, and 1973 Jamborees (Aldridge).
For the 2010 Jamboree, additional flaps were also created for the OA Indian Village, Mysterium Compass, as well as an 100th Anniversary and a Thank You flap. For the 2013 Jamboree, additional flaps were also created for the OA Day of Service, OA Trek Guides, OA Indian Village, and a OA Staff Thank You flap. Starting with the 2017 Jamboree, an expanded Operation Arrow program with a commemorative flap set that included flaps for the Aerial Sports Team, OA Exhibit, OA Trek Guides, OA Indian Village, Medical Transport Corps, and Headquarters Team.
At the 2015 NOAC, endowment flaps were sold to celebrate recipients of the OA Distinguished Service Award and the Founder's Award.
In 2018 and 2020, flaps were issued for the OA Summit Experience at SBR, the OA Trail Crew at Philmont, the OA Ocean Adventure at Florida Sea Base, the OA Wilderness Voyage at Boundary Waters Canoe Area Wilderness, and the OA Canadian Odyssey at Quetico Provincial Park.
In 2019 the National Council created Wewikit Lodge, mainly for professionals and the National Chief and National Vice-Chief. Volunteers and professionals attending the National Planning Meeting in December were each given a flap badge from this lodge (Minnihan and Shelley). According to patchscan.com, 350 were manufactured by Moritz Embroidery in July of that year. In my opinion, these are more akin to the discontinued National Committee flaps.
For the 2023 Jamboree, Operation Arrow was described as an
"opportunity to experience the 2023 National Jamboree, with the option to serve on Jamboree staff with the OA Service Corps or the OA Summit Apex Program. The OA Service Corps is our traditional service-oriented team that has supported jamboree programs and operations since 1950. It's a great way to serve and see many different aspects of the jamboree. As a member of the OA Service Corps you will be formed into 'chapters' that provide support to jamboree program and operations. This may include supporting contingent arrival, assisting with jamboree program staffing, jamboree show mobilization and more. The Summit Apex is a new half-day outpost program area that will inspire Scouts to realize and truly appreciate the benefits of their Scouting membership. Scouts will engage in large-scale activities, a unique jamboree dinner experience, and evening reflection/celebration that will leave them with a renewed enthusiasm for Scouting and a determination to grow membership back home."
Also, a commemorative flap set was issued that included flaps for the OA Alliance, OA Program, OA Service Corps, Summit Apex, and Management Team.
