Name two major Pacific World War II campaigns featuring Marine operations on islands.

• A. Okinawa and Peleliu
• B. Guadalcanal and Saipan
• C. Guadalcanal and Iwo Jima
• D. Iwo Jima and Tarawa

Answer: (C)

Two major Pacific campaigns in which Marines conducted island fighting were Guadalcanal and Iwo Jima. Guadalcanal, from August 1942 to February 1943, was the first sustained Allied offensive in the Pacific and introduced the successful island-hopping approach, with Marines and sailors fighting through dense jungle to seize and defend Henderson Field while repelling Japanese naval and ground counterattacks. Iwo Jima, in February to March 1945, came later and represented a climactic, heavily fortified assault aimed at capturing airfields close to the Japanese home islands to support bombing missions and provide a base for operations; the fighting was famously severe, underscoring the willingness of Marines to endure extreme costs for strategic gain. Together, these campaigns illustrate the arc of Marine island warfare in the Pacific—from the breakthrough offensive that began turning the tide to the brutal, near-home-front battles that pushed toward Japan. Other island campaigns like Tarawa, Peleliu, Saipan, and Okinawa are also major, but Guadalcanal and Iwo Jima best capture the progression and significance of Marine operations across the theater.
