activity incident to service
activity incident to service. An act undertaken by a member of the armed forces as a part of a military operation or as a result of the actor’s status as a member of the military. • For example, if a member of the military takes advantage of that status by flying home on a military aircraft, the flight is activity incident to service, and a claim against the government for any injuries received may be barred under the Feres doctrine. See FERES DOCTRINE.
