Due to the overwhelming number of soldiers demanded to travel to the frontlines of World War I, the depot revamped the training regiment recruits endured, the number of recruits taken grew, and expansion occurred. Recruitment numbers fell during the Great Depression of the 1930s before becoming overwhelmingly large after the bombing of Pearl Harbor and beginning of U.S. involvement in World War II in late 1941. After the passage of the Women's Armed Services Integration Act of 1948, the base began training the first set of women's recruits followed by African-American recruits being welcomed to the depot in 1949.
During the training periods in the years of the Vietnam War, the length of recruits' training lowered from the usual twelve week program to ten weeks in order to avoid adding more platoons as over 200,000 enlisted to become Marines. The current structure of the training was implemented in 1996 that included values-based training, the introduction of the infamous fifty-four-hour culminating mission known as the Crucible, and the reintroduction of a twelve-week training period for both male and female Marine recruits. Through the storied history of the Corps and the Depot, it is easy to understand why the Marines are one of, if not, the highest regarded branches of military service.
The public is welcome to visit the museum, whether they are just wanting to see the museum itself or have traveled to see their family member graduate from Parris Island. If arriving on a family or graduation day, guests will experience some delays as the base will be crowded over the two days of events. After leaving the museum, guests will have a new found respect for not only the Marines who call the area home for however long their training may last, but for the citizens of the town who hold a tradition and legacy of bravery and progress that benefits the nation to this day.
