Burial flags used for military honors at Arlington National Cemetery measure 5' x 9 ½'. Most funeral homes will obtain the U.S. Flag on behalf of the veteran's family. Requests for a burial flag must be made at the time of need (time of death). Burial flags may be obtained from VA regional offices and most U.S. post offices by completing VA Form 21-2008, Application for United States Flag for Burial Purposes, and submitting it with a copy of the veteran's discharge papers at either of the locations. You can also download the Application for United States Flag for Burial Purposes form online from the Department of Veterans Affairs website.
