The military/Army obstacle course is used (mostly in recruit training). The purpose is to familiarize recruits with the kind of military tactics they will use in combat. It is also for physical fitness, building teamwork, and evaluating problem solving skills. Typical courses involve obstacles the participants must climb over, crawl under, balance, hang, jump, etc. Puddles of muddy water, ropes, nets, and "no touch" restrictions are often used to make the course more difficult.
