assume &quot;last 20&quot; was on active duty? if so, seems like you and i joined the corps at about the same time. i didn&#x27;t re-up after 4, but agonized over that decision for the last six months of my tour. in the end, obvious to me that &quot;another four&quot; might as well be 20, and i was too immature to make that decision. (sgt in echo 2&#x2F;5, btw)
