tour of duty

Luke Shipman never remembered the nights he was screaming in terror after a tour of duty in Afghanistan.

After a four-year tour of duty that included a posting in Japan, he got a job at Lockheed Martin, where he worked for the next 45 years, she said.

When his first tour of duty ended he vowed not to return.

It was a very interesting nine-month tour of duty in military service, tactical training, and of course the medical aspect of evaluating injuries, administering morphine, splinting and stopping bleeding.

He decided to stay with his unit until the end of his tour of duty in May.
