USS Hunterdon County saw extensive service during the Vietnam War, operating as part of Operation Game Warden, a brown-water navy effort to keep the rivers free of Viet Cong infiltrators. On 12 May 1970, it was the first U.S. Navy commissioned vessel to enter Cambodia, rearming and refueling helicopters that belonged to the U.S. Army and Navy, as well as the Air Force of the Republic of Vietnam. According to "The Jackstaff News," the official Navy paper for "U.S. Naval Forces II, III, and IV Corps Vietnam":

The Hunterdon County was the first U.S. ship to cross the Cambodian border, 12 May [1970], after President Nixon's decision to enter that country. It remained there and continued to provide support to the Vietnamese armed forces and their U.S. Army and Navy advisors longer than any other ship of its type, according to Navy officials.

The ship's credits in Vietnam include capturing one of the largest Viet Cong caches in the Delta on 29 March 1969, and establishing the record for the furthest transit of the Bassac River by a U.S. commissioned vessel in August of that same year. 

A valuable addition to your Vietnam war military memorabilia collection.
