Best & worst of in-processing & out-processing?

BEST part?
Probably Squadron/Platoon tour since that's when you meet all the people you're going to get to know best.

WORST?
Finance. They always hold the oddest hours they can get away with, there's always a line, the waiting area is usually too small, and there's always something wrong with or missing from your paperwork.

And tomorrow is a day when they aren't even open, unless it was today.

For Outprocessing it's juggling packing and being mostly packed in the last week before you leave and having people give you gifts that now have to be packed that's the worst. Best part depends on too many external factors to pin down, but I'll go with unpacking at the next stop.

The worst unit I have ever seen for in or out processing are Air Combat Command. The best was 62 airlift wing.

When I returned from Iraq as an augmentee, we were driven from the plane to CIF. We did not have to clean anything, just account for and turn things in.
