When your son or daughter steps onto the yellow footprints, they join a line of recruits that stretches back more than a century. Marine Corps recruit training has changed a great deal over that time, through two world wars, Korea, Vietnam and the modern era, yet its purpose has stayed the same: turn civilians into Marines who share the same standards and values. Knowing that history can help families understand why boot camp looks the way it does today.

Parris Island: Where It Began
Marines were present around Port Royal Sound long before boot camp existed. A small Marine guard was posted there in 1891 to protect a naval facility, and a recruit depot operated at Port Royal briefly starting in 1911 before moving to Norfolk, Virginia. In October 1915 the recruit depot returned to Port Royal with the main mission of training enlisted Marines, and training began on Parris Island in November 1915.
World War I brought the first major test. The depot expanded rapidly, and about 41,000 recruits trained there during the war. The island’s name was also settled in this period: it had been spelled “Paris,” and a 1919 Marine Corps order officially changed it to “Parris.”
San Diego and the West Coast
As the Marine Corps grew, it needed a training site in the West. The San Diego base was formally commissioned in 1921, and in 1923 it became the primary West Coast recruit training center when training moved there from a Navy base in Vallejo, California. The installation took the name Marine Corps Recruit Depot San Diego in 1948.
To this day, San Diego recruits complete part of their training away from the depot. They spend several weeks at Edson Range aboard Camp Pendleton for rifle qualification, field training and the Crucible, then return to San Diego to graduate. Parris Island recruits complete all of their training on the island itself.
World War II, Korea and Vietnam
World War II stretched both depots to their limits. Parris Island alone trained roughly 200,000 recruits during the war, and training periods were shortened in the early months to meet demand, then lengthened again when gaps in preparation became clear. During the Korean War, the flood of recruits outpaced the supply of experienced drill instructors, which led to the re-establishment of a formal Drill Instructors’ School. Parris Island graduated about 138,000 Marines during that conflict.
In 1956, six recruits drowned during an unauthorized night march into Ribbon Creek at Parris Island. The tragedy led the Commandant to order closer supervision of drill instructors and of recruit training as a whole, and it remains an important lesson in the depot’s history. During the Vietnam War, more than 200,000 recruits trained at Parris Island, and training was shortened from 12 to 10 weeks to keep up with the numbers.
Women Marines and Integration
Women have served as Marines since 1918, when Opha Mae Johnson became the first woman to enlist. After the Women’s Armed Services Integration Act of 1948, the Marine Corps began training women as regular Marines, and the first female recruits arrived at Parris Island in February 1949. For decades Parris Island was the only place enlisted women could earn the title Marine. In 1986 that mission was assigned to the newly created 4th Recruit Training Battalion.
Change came in stages. In early 2019, India Company at Parris Island trained one female platoon alongside five male platoons, making it the first partially gender-integrated company. Male recruits began training within 4th Battalion in the following years. In February 2021, a platoon of female recruits began training at San Diego for the first time. By 2022 all recruits were training in gender-integrated companies, and the 4th Recruit Training Battalion was formally deactivated in June 2023. Both depots now train men and women.
The Crucible and Modern Boot Camp
In December 1996, recruit training was revamped to place more emphasis on values-based training, and the Crucible was introduced. This 54-hour event tests recruits with limited food and sleep, long marches and team problem-solving, and it serves as the final step before they earn the Eagle, Globe and Anchor. Training for male and female recruits was aligned to the same schedule at that time.
Today boot camp lasts about 13 weeks. Recruits learn drill, Marine Corps history, customs and courtesies, marksmanship, swimming, martial arts and combat conditioning, and they must meet set standards to graduate. Roughly 20,000 recruits come through Parris Island each year, with San Diego training the rest.
What This History Means for Your Family
The traditions your recruit meets, from the yellow footprints to the Crucible, were shaped by more than a hundred years of experience, including hard lessons learned along the way. When you sit in the stands on graduation day, you are watching the newest chapter of that story. Your Marine will graduate alongside men and women from every part of the country, connected to every generation that trained before them. That shared history is a big part of why Marines feel such a strong bond with each other, and why many families find themselves feeling part of it too.
Frequently Asked Questions
How long has Parris Island trained Marine recruits?
Recruit training has taken place on Parris Island since November 1915. Marines trained there during every major conflict of the 20th and 21st centuries.
Do women train at both recruit depots now?
Yes. Women trained only at Parris Island from 1949 until 2021, when the first female recruits began training at San Diego. Since 2022, recruits at both depots have trained in gender-integrated companies.
When was the Crucible added to boot camp?
The Crucible was introduced in December 1996 as part of a broader update to recruit training. It is a 54-hour test that recruits must complete before earning the title Marine.
Why do some recruits go to San Diego and others to Parris Island?
Assignment is generally based on where a recruit enlists. San Diego has historically trained men recruited west of the Mississippi River and some other areas, while Parris Island trains recruits from the East. A recruiter can confirm which depot applies to your recruit.
