How does DTS differentiate between "TDY" and "PCA" orders?

The distinction between “TDY” (Temporary Duty) and “PCA” (Permanent Change of Assignment) orders is fundamentally about the duration and nature of the assignments. TDY orders are specifically designed for short-term travel assignments, where personnel are temporarily assigned to a location for official reasons, typically lasting for a few days to several months. These assignments allow personnel to fulfill mission requirements while still being connected to their primary duty station.

In contrast, PCA orders represent a permanent change of station, indicating that an individual is moving their primary duty location on a more enduring basis, which is a significant transition in their career. This differentiation is crucial for personnel management, budgeting, and planning travel logistics.

The other choices do not accurately capture the essence of the TDY and PCA definitions. Each option presents misunderstandings about the policies associated with these types of orders. Understanding the differences helps military and civilian personnel navigate travel and assignments appropriately.
