I'm collecting SS.
It was my understanding that they don't add extra money to my SS check.
What they did do-------they gave me extra credit for those 2 years I earned military pay( 1965-1967)
However, since your SS benefits are calculated by using your 35 highest earning years, I doubt those 2 years made any difference in my case.
I believe the benefit, for most, is so small it is undetected.
I appreciate the " cosmetic" effect because at least I didn't get penalized
for the 2 years I served.
That very low military pay in the 60's was enough of a penalty.
