Vietnam war in-country embroidered patch measures approximately 3.4" by 3.4". "TRANH DAU HOA BINH" means "Fight For Peace".

During the Vietnam war, A Company 502nd Aviation Battalion was deactivated in September 1966 and the 175th Aviation Company activated in its place, from personnel and equipment formerly assigned to A/502nd and retained their call signs "OUTLAWS". On 2 November 1967, the 175th Aviation Company was redesignated as the 175th Assault Helicopter Company and retained that designation until deactivation in February 1972 in Vietnam.

A valuable addition to your Vietnam war military memorabilia collection.
