The Southern Cross of Honor is used as an emblem or marker on the graves of Confederate veterans who served honorably. The cross is still available to be placed as an emblem on all United States Government-furnished headstones or markers. This emblem will only be issued by the U.S. Department of Veterans Affairs to be placed on the grave of a Confederate veteran (Wikipedia).
Note; the Confederate battle flags are banned from most locations. Over time the flag has been adopted by nationalist organizations, racist groups, besides always having been associated with slavery. Flags cannot be prohibited on private property. This cemetery is owned by a private organization, a military cemetery including the CSA is inside the grounds.
