This is the best advice I can give you, have the job related stuff ready to upload for any announcement. Do not just upload what people suggest. There will be a list of required documents towards the bottom of the page. It is VERY important that you read the application steps carefully and upload the required documents stated in the announcement. Not every announcement on USAJobs is the same for Air Traffic. With that being said, fill up your available documents section on your USAJobs account. Put all of your supporting documents there, "pink card", 3622, statement of service, DD214 (when you get it), anything that supports the fact that you have held ATC ratings and served in the military.
