This is distinct from a permanent change of assignment (PCA), which describes the reassignment of active duty personnel to a new unit within the same military post.
This term is also used for other United States government employees, such as a Foreign Service Officer, special agent, diplomats, and other civilian, non-military personnel, being stationed in embassies and consulates around the world.
In contrast, a temporary duty assignment is a shorter-term change of station, usually less than six months.
