In the US the FAA has a vacancy announcement that is aimed at recruiting current military controllers who are approaching military retirement. The FAA also gives preference to military controllers who are getting out / or are out of the miltary prior to reaching retirement age. Just a reminder you have to be a US citizen to work for the FAA.
At my facility we have 4 former military controllers (all uder age 30), one was so sharp in the training program (military approach control experience), we had to reduce the minimum hours required so that we could certify him early, and he has already moved onto a busier facility. Another cetified in the normal amount of time, and the other two are still plugging away. All four arrived at the facility the same day. As you can see having approach control experience was a huge asset for the one individual.
