Time spent in a hostile or combat environment
For military personnel, a tour of duty is usually a period of time spent in combat or in a hostile environment. In an army, for instance, soldiers on active duty serve 24 hours a day, seven days a week for the length of their service commitment. Soldiers in World War II were deployed for the entire war and could be in active service for 4–5 years.
