Just a quick aside to an earlier post,
I think sending an Air Force Academy picture to a marine would be pretty funny. If this marine is an officer, he might have gone to the Naval Academy since this is where some of the officers are trained. If an enlisted marine is sent to the USNA, then they have to resign from the marines and become Navy for their time at the Academy. The firsties do service selection between marines and navy and hopefully get their first choices, whether is it Marine ground or Navy Air or SWO or Marine air or subs. There are instances were the graduates are able to change their service branches as well. This past year, I know of at least one grad who went Air Force. If this marine went to USNA, then a post card of West Point could also be pretty humorous.
