The Tuskegee Airmen are remembered. The World War II-era U.S. Army Air Corps unit was home to the nation's first black military airmen.

In 1950, the United States promises to liberate Seoul, South Korea, from North Korean control.

The work of JPAC (Joint POW-MIA Accounting Command) to account for missing Americans from past conflicts and wars is highlighted. Included: the search for Army Maj. Frederick Joel Ransbottom, who was reported missing in Vietnam in 1968; the story of 19 Marine Raiders who were lost on Makin Island in 1942.

The Afghanistan War is examined. Included: the efforts of U.S. forces against the Taliban; the training of Afghan security forces.

In the spring of 1972, the exodus of US troops from South Vietnam left only a small number of American military advisors. These few men, dedicated to Vietnamese freedom, were assigned to South Vietnamese units and scattered throughout the country. To North Vietnam’s General Vo Nguyen Giap it seemed the perfect time to strike a final, deadly blow, and capture all of Vietnam. On Easter Weekend, Giap launched the largest invasion of the war.
