I could be wrong, but I think I remember reading somewhere that once you serve 20 years outside of the academy the 4 you spent at the academy start counting toward your pay and retirement.
I'd like to know why USNA69 was banned...
After 20, the four years DO count, not an urban myth - current mid
kp, that is correct. Your SA and service time an be bought be back toward a retirement... Source... My neighbor and best friend did this. I have a copy of the document that references it as I had several GS offers I considered.
And the 4 years at a SA do not get tacked on 'at the end' to make a 20 year retirement now 24... I asked several of my close friends who retired in the last 6 months. None of them had that time added on.
