World War II: American forces land on Kwajalein Atoll and other islands in the Japanese-held Marshall Islands.

Kwajalein Atoll is part of the Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents often shorten to Kwaj. The total land area of the atoll is just over 6 square miles (16 km²). It lies in the Ralik Chain, 2,100 nautical miles southwest of Honolulu, Hawaii.

The Marshall Islands, officially the Republic of the Marshall Islands, is an island country west of the International Date Line and north of the equator in the Micronesia region of the Northwestern Pacific Ocean.
