No, but I am going to the Marine Corps Officer Educator's Workshop next week. They're flying me to Virginia, and I'll watch potential officers go through their training. Specifically, they're young folks whose summer job is going through Marine Corps training, but without having to make a commitment to the Corps. They can do this for two or three (I think) years, and then they are given the option of committing to the Corps after graduating college. If they do, they go to an abbreviated OCS and become officers. If they don't, they part ways amicably and owe the Marines nothing.
The recruiting officer who nominated me for the program said the great majority who go through the program do commit to the Marines, but the Corps isn't interested in making the commit prior to that, because they only want those who really want to make a real commitment.
I'm looking forward to observing their training program and learning more about the history of the Marines. I'm not sure, but I think I'm going to be at Quantico. That's where the National Museum of the Marine Corps is, which has the flag that was raised on Iwo Jima both of them, actually).
Sometimes I'm amazed at the opportunities that come my way.
