Located in South Korea, the Osan Air Base has been used by the United States Military since 1952. The Osan Air Base has been utilized in operations during the Korean War, the Cold War, and the Vietnam War. To honor those on the Osan Air Base, we have designed custom Osan Military t shirts. All Osan Military T Shirts have a unique design on the back to commemorate US forces at the Osan air force base. Pick one up today as a memento of your overseas tour!
