I’m not trying to put you off, but we’ve had two such conversational threads very closely related to what you’re asking. In fact one of them was also from a someone currently in the service.
Congratulations and thanks to you for serving in our armed forces. Although various services tease and compete with each other – veterans of all services understand that you’ve put yourself at risk to help protect our way of life.
I just did a quick search with just “college” as the keyword. As you might expect, your query came up first (most recent), but some of the other threads came up – and I think that you’ll find those threads helpful and informative. I was amazed at the thought and insight that went into many of those replies.
After you’ve read those, you’ll probably have more questions, so please feel free to post again.
