The Second Battle of Khe Sanh (Jan 1968) involved Marines defending a firebase for 2.5 months from North Vietnamese attacks. Which battle is this?

• A. Battle of Hue City
• B. Second Battle of Khe Sanh
• C. Battle of Okinawa
• D. Battle of Iwo Jima

Answer: (B)

This question tests your ability to recognize a famous siege from the Vietnam War by its setting and duration. The description—Marines defending a firebase for about 2.5 months starting in January 1968 against sustained North Vietnamese attacks—fits the siege at Khe Sanh, where Marines at a base near the DMZ endured a long, intense fight from January through April 1968. The other options refer to different conflicts or battles: Hue City was a brutal urban fighting scene during the Tet Offensive in February 1968, while Okinawa and Iwo Jima were World War II island battles in 1945. So the event described is the Second Battle of Khe Sanh.
