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. [Blacks Law 8th]
