19 Part One: Boot Camp is a multi-load computer game created by Cascade Games in 1988. It appeared on the Commodore 64 and ZX Spectrum. The inspiration for the game came in two parts - the arcade game Combat School and the Paul Hardcastle song 19, which was itself about the Vietnam War.
The player controls a soldier through several training events, including an obstacle course, shooting practice and jeep driving.
