The Cold War resulted in the Korean War and the Vietnam War.
I am pretty sure you can't be drafted, unless the country is in some major war like WWII and there are no reserves left. During WWII and the Vietnam War men were drafted into the Marine Corps as well as the Army so - yes - some registered with Selective Serviece CAN be drafted into the Marine Corps. As a practical matter, it has only happened during "major war" such as that alluded to by the first person who answered this question. If my sources are correct, most of the Marines during WWII were drafte, 16,000 men were drafted into the Marines during the Korean War and 42,633 drafted into the Marines, during the Vietnam War. No one has been drafted since the Vietnam War, but the possibility still exists.
