It means what it says it means..if they are settled into a prison camp (Afghanistan, Gitmo) and are being transferred, it means they will be transported for resettlement into another facility.
We use the U S Marshalls for transport of federal prisoners, but that is U S citizens....not military detainees.
Nope. Military prisoners of war are simply transferred from one military detention facility to another. Civilians are "resettled," often against their will by state order.
