^^^^^^ THIS!!!!!

It's actually pretty hard to get to five years that counts against the USERRA limits. Although it's more likely in the guard than federal units.

If you break down the deets of your active duty time while at your current employer, I can give you a good analysis.

For starters: drills and regular annual training type duty does not count. Your initial AD training does not count, including seasoning. Any AD required due to an incurred obligation does not count. It's actually possible to get an airline job, leave for a full 20-year career in the regular active duty forces, and come back to your original DOH seniority... would require some creative obligation incurring, but can be done (the first ten years is a freebie for wings obliserv).

Most AD in support of contingencies doesn't count either, so almost anything over-seas or in support of training and readiness for AD units is free.

Prior to the AFG withdrawal, pretty much only duty which was disconnected from operational AD training and readiness would likely count. Examples: war college instructor on three year orders, maybe AGR supporting guard unit admin.

Also as was mentioned, ask your employer what their policy is it, it may be more liberal.
