This clip shows a number of activities in the Marine Corps.

Marines are in a classroom taking a test. A man is at the head of a classroom pointing to what is most likely an engine while Marines take notes at their desks. A Marine works on a satellite in the desert as a balloon is released into the sky. Quicks shots in succession show a man working at a control board, missiles being pointed at the sky, a tractor pushing dirt, welding, kneading dough, a marching exercise, air marshalling, two people boarding an aircraft, land surveying, a military aircraft flying and a bird’s eye view, and a Marine driving a US Marine Corps truck.
