A permanent change in assignment means moving to a different unit or duty location and staying there long-term, without changing rank or pay. That’s what a transfer describes: you relocate to a new assignment and remain in that role, rather than returning to the old one or taking on a temporary stint. A detail position is typically temporary, used to gain experience or cover a short-term need, and will end after a defined period. Reassignment can refer to moving to another assignment within the department, but for a lasting move without a change in rank, the term used is transfer. Promotion involves moving up in rank or pay, not just changing where you work. So the permanent, non-promotional change in assignment is transfer.
