Reminiscent of our war with North Vietnam, this Zippo was probably used by a local veteran during his tour of duty. Zippos, including those associated with wartime activities, are very collectible.

In the Vietnam War, the Mobile Riverine Force
(MRF) (after May 1967), initially designated Mekong Delta Mobile Afloat
Force, and later euphemistically the Riverines, were a joint US
Army and US Navy force that comprised a substantial part of
the Brown Water Navy. It was modeled after lessons learned by the French
experience in the First Indochina War and had the task of both
transport (of soldiers and equipment) and combat. The primary base was
at Đồng Tâm Base Camp, with a floating base at the base of the Mekong
River. It played a key role in the Tet Offensive.
