The Roy T. Church Vietnam War Collection is primarily comprised of slides and photographs related to the 1965-1969 military service of Roy T. Church, a bombardier and navigator for the United States (U.S.) Marines during the Vietnam War. The majority of the photographs, which are informal snapshots, depict military life in Vietnam and military aircraft during the war. Some of the photographs were taken by Church.

The collection contains 63 color slides that feature military personnel, such as unidentified soldiers in casual settings, as well as next to and aboard aircraft; military buildings, including bunkers and hangars; Church's military training, including his time on the USS Lexington from 1965-1967; scenic shots of Vietnamese rural life, including shots of civilians and children; aircraft, in flight and on the ground, including a Grumman A-6F Intruder; and several aerial shots, likely over Vietnam and Laos. Additionally, there are a few images of the North Cascade Mountains in Washington State, circa 1967.

There are also 14 snapshots. The images mostly feature soldiers in a variety of settings, including marching on patrol, performing repair work, posing next to buildings, handling guns, and at award ceremonies. There is also a group portrait, likely a graduation shot, in front of a building with a sign over the door, "U. S. Naval Aviation Schools Commands, Battalion Two." Other pictures feature aircraft, including a shot of a Grumman A-6F Intruder being refueled in flight and a "crispy critter" (per the donor: an aircraft bombed by the Viet Cong forces).

At the end of the collection is a partial map of Vietnam, which has been folded over and taped to a rectangular piece of cardboard.
