I went to the US Army's "Spirit of America" show last weekend-- featured bands and the Silent Drill Team, as well as some re-enacting of key Army history moments. Of course, I did some musing about my non-existent Army career (rejected from ROTC).
I was shocked to calculate that IF I had been commissioned when I wanted to, summer 1990, I would be one year from the magic number of 20 for retirement!
Assuming, of course, I didn't quit in the '90s or die or something else, of course.
