During World War II, the division was credited with many "firsts". It was the first United States division to deploy as an entire unit overseas and among the first of seven U.S. Army and U.S. Marine units to engage in offensive ground combat operations during 1942. The division was among the first divisions to engage the enemy and were still fighting holdouts after the official Japanese surrender. The 32nd logged a total of 654 days of combat during World War II, more than any other United States Army division. The unit was inactivated in 1946 after occupation duty in Japan.
