Ducanger Prison IV

The Ducanger Prison IV is functioning Vietnamese prison located in Bến Tre Province,South Vietnam. It will be owned by Ngo Dinh Diem and Ducangers, which it was one of 6 Ducanger Prisons (whilst the Ducanger Prison VII project is unfinished due to the Liberation of Saigon).

Only happened before ARVN troops capture Sunset Shimmer and her girls that it would be built by the Army of the Republic of Vietnam.

When most of pony P.O.W.s are either Equestrian soldiers or Equestrian ponies, only ARVN pony guards (Equestrian traitors who joined Ducangers and ARVN) can guard this prison due to only pony allow after ARVN ordered.
