That is true you can only be in the DEP for no more than 365 days, you choose your ship date, they dont. I dont know where you got that from CO. I chose my own ship date.
For the test, as with all services you take the ASVAB. That tells them, 1. If you qualify, 2. What kinds of MOS's you qualify for.
I dont believe the MC looks at what kind of clubs you are in, they do however look at what kind of sports you play, if any.
LOL, I like your question on what they look for in a human being. I believe they look for honesty, courage, and somebody who will commit.
I think you have a good plan, but you might be getting ahead of yourself a little.
Hope this helps.
