I think Wannabe was what we (at VMI) used to call a "Hotsy Totsy Rotcee Nazi" .... but he he might have been OCS. Only thing for sure is he not a trade school or military college product. (Of course, there's always Conroy, whose 'come to Jesus' meeting with himself was over 30 years late, who was a military college (Citade) product, but he was the exception rather than the rule)
The thing that made me suspect his motives for joining was that he was commissioned the summer after the invasion and his family is involved in democratic politics in Hawaii.
