If I go to TBS without an air contract, but want to fly, is there a good chance that I won't be able to get a slot? I know that they split the class up into thirds and give first picks to the people who are tops in each third. It seems to me that you need a little luck to get the MOS you want. I know this is a tough question, and depends a lot on the needs of the Marine Corps, which are constantly changing, but any insight would be appreciated. Thanks.
