Thanks for posting. Very clear and interesting. “...provide accompanying vaccination documents as proof of their status.” Sad that private, medical information is now to become public information.
I should have added that you should have access to a retirement calculator. The Navy uses something called the GRB platform that contains all an employees employment data. I think this system is DoD wide, maybe all federal agencies use it.
There is a retirement tab that includes a calculator. It is very straightforward just plug in different dates and options to see what you will get.
Let me know if you need more info on this.
