Of course, the majority of them have always gone to the Army instead of the Marines, that was true in WWII and Korea and Vietnam.
It was a good system in my opinion and were it in effect now, it certainly would have assured that some of the Bush, Romney & Sununu boys (among others) would have served in uniform (yes I am aware of the 'my people' Bush's quickie JAG tour...). Now we've got a hugely expensive recruited force that most likely could not handle another Korea if we had to do it. Fortunately the South Koreans are largely able to care of themselves, especially on the ground.
