# 3.313 Claims based on service in Vietnam.
(a) *Service in Vietnam. Service in Vietnam* includes service in the waters offshore, or service in other locations if the conditions of service involved duty or visitation in Vietnam.
(b) *Service connection based on service in Vietnam.* Service in Vietnam during the Vietnam Era together with the development of non-Hodgkin's lymphoma manifested subsequent to such service is sufficient to establish service connection for that disease.
(Authority: 38 U.S.C. 501)
