Marine Corps recruit training is 13 weeks long, and it is widely considered the most demanding entry-level training in the U.S. military. The good news is that the weeks and months before shipping out are a real opportunity. Recruits who arrive in shape, mentally ready, and with the right expectations tend to handle the stress far better than those who show up hoping to figure it out on the yellow footprints. This guide walks recruits and their families through what to do now, what to expect later, and how parents can help without getting in the way.
Quick Facts: Marine Corps Boot Camp at a Glance

- Contact with home: One short call on arrival, then letters until after the Crucible
- Family Day: The day before graduation, the first chance to visit your new Marine
The Delayed Entry Program: Where Preparation Starts
Most recruits do not ship to boot camp the day they enlist. They join the Delayed Entry Program (DEP) and become “poolees” while they wait for their ship date, which can be weeks or months away. This waiting period is one of the biggest advantages a recruit has, and it should not be wasted.
During DEP, recruiters hold regular sessions, often called pool functions, where poolees work out together, practice the IST, and start learning basic Marine Corps knowledge such as ranks, general orders, and history. Poolees who show up consistently get a head start on both the physical and mental side of training. Recruiters also use this time to make sure paperwork, medical records, and fitness scores are in order before ship day.
Parents can help simply by treating DEP as part of training rather than a break before it. Encourage your poolee to attend every function, keep their recruiter informed of any changes, and stay out of trouble. Legal problems, injuries from risky activities, or new medical issues can delay or even cancel a ship date.
Physical Preparation and the Initial Strength Test
The Initial Strength Test is the Marine Corps’ minimum fitness standard for shipping to recruit training. Recruits take it with their recruiter before they ship and again during the first phase of boot camp. According to the Marine Corps’ official recruiting standards, the IST has three events:
- Pull-ups or push-ups: Males must complete 3 pull-ups or 34 push-ups in 2 minutes. Females must complete 1 pull-up or 15 push-ups in 2 minutes.
- Plank: All recruits must hold a plank for at least 40 seconds.
- 1.5-mile run: Males must finish in 13:30 or less. Females must finish in 15:00 or less.
These are minimums, not goals. A recruit who barely passes the IST will find the daily physical training, hikes, and obstacle courses much harder than one who arrives well above the line. Standards can change, so always confirm the current numbers with your recruiter before ship day.
How to Train Before Boot Camp
- Run consistently: Build up to several runs a week, mixing steady distance with faster intervals. Running is where many recruits struggle most.
- Practice pull-ups often: Pull-ups improve with frequent, short sets. If you cannot do one yet, start with hangs, negatives, and assisted reps.
- Strengthen your core: Planks, both front and side, build the endurance needed for the IST and for carrying gear.
- Walk and hike with weight: Boot camp includes long hikes. Walking with a loaded pack in broken-in boots or sturdy shoes helps prepare feet, hips, and back.
- Increase gradually: Stress fractures and shin splints are common in new recruits. Add mileage and intensity slowly, and rest when something hurts.
- Learn to swim: Recruits go through combat water survival training. Strong swimmers have one less thing to worry about.
Habits matter as much as workouts. Getting up early, sleeping on a regular schedule, cutting back on junk food and energy drinks, and staying hydrated will make the adjustment to recruit training much easier.
Mental Preparation: The Part Most Recruits Underestimate
Many recruits arrive physically ready and still have a rough first few weeks. The challenge is usually mental. Boot camp removes almost every comfort and choice recruits are used to. They will be told when to wake, eat, speak, and sleep. Drill instructors will be loud, fast, and demanding on purpose, because pressure is part of how the Marine Corps teaches discipline and teamwork.
A few things help recruits get through it:
- Expect the yelling and do not take it personally. It is not about them as individuals. It is a training tool.
- Focus on one day at a time. Thirteen weeks feels long. One meal, one class, one evolution at a time is manageable.
- Pay attention to details. Small things like following instructions exactly and moving with urgency matter enormously.
- Learn knowledge early. Studying rank structure, general orders, and basic Marine Corps history during DEP frees up mental energy later.
- Remember why they joined. Recruits who know their reasons tend to hold on during the hard days.
What to Bring and What to Leave at Home
The Marine Corps issues nearly everything a recruit needs, from uniforms to hygiene items. Packing light is the rule. The recruiter will provide an official list for each recruit’s ship date, and that list always takes priority over general advice.
Usually Needed
- Valid photo ID such as a driver’s license or state ID
- Social Security card
- Any documents your recruiter specifically requests
- Addresses of family and friends written on paper, since phones will be stored away
- The clothes you travel in, which should be plain and comfortable
Best Left at Home
- Valuables and jewelry
- Large amounts of cash
- Extra clothing and bags
- Electronics, which will be stored until much later in training
- Anything that could be considered contraband, including weapons, tobacco, alcohol, and unapproved medications or supplements
Personal items that recruits do bring are inventoried and stored, so less really is better.
Parris Island or San Diego?
The Marine Corps has two recruit depots. Assignment is generally based on where a recruit enlists. Recruits from west of the Mississippi River usually train at Marine Corps Recruit Depot San Diego in California, while recruits from the east usually train at Marine Corps Recruit Depot Parris Island in South Carolina.
Both depots follow the same program of instruction and produce the same Marines. For many years, all female recruits trained at Parris Island. That changed in 2021, when the first female recruits trained and graduated at San Diego. Today women train at both depots. The settings differ: Parris Island sits on the South Carolina coast with hot, humid summers, while San Diego recruits complete part of their training, including rifle qualification and the Crucible, at Camp Pendleton with its steep hills.
The 13-Week Timeline: What Happens When
Recruit training is divided into four phases. Exact schedules vary by depot and company, but the overall flow looks like this.
Receiving and Phase One: Foundation
Training begins when recruits step onto the famous yellow footprints. In the first days, called receiving, they get haircuts, uniforms, medical and dental screening, and paperwork. They also make one short, scripted phone call home to say they arrived safely. Once they are assigned to a platoon and meet their drill instructors, Phase One focuses on in-processing, the Initial Strength Test, drill, discipline, and basic knowledge.
Phase Two: Immersion
This phase builds endurance and confidence under pressure. Recruits complete combat water survival training, physical and combat conditioning, Marine Corps Martial Arts Program instruction, and continued academic classes.
Phase Three: Transformation
Recruits move into marksmanship, field training, tactical skills, and team problem solving. This phase leads up to the Crucible, a 54-hour event with limited food and sleep and about 45 miles of marching. At the end of the Crucible, recruits receive the Eagle, Globe, and Anchor emblem and are called Marines for the first time.
Phase Four: Transition
The final weeks include final physical and academic testing and preparation for graduation. New Marines also get limited phone and internet access during set periods after the Crucible. Family Day takes place the day before graduation and is usually the first time families can see their Marine in person.
After graduation, new Marines typically take about 10 days of leave before reporting to the School of Infantry. Infantry Marines attend a longer infantry course, and all other Marines complete Marine Combat Training before moving on to their job schools.
What Parents Can Do
Watching a son or daughter leave for boot camp is hard. You will go from talking every day to hearing almost nothing for weeks. Here is how families can help most.
- Support the preparation. Encourage workouts, good sleep, and attendance at pool functions. Offer to run or hike with your poolee.
- Keep the goodbye positive. Recruits carry the tone of that last conversation with them.
- Be ready for the arrival call. It will be brief and scripted. It is simply a confirmation that they arrived safely.
- Watch for the first letter. According to the Marine Corps, it usually arrives 7 to 9 days after the recruit gets to the depot and includes their mailing address.
- Write often and keep it encouraging. Letters are the lifeline. Share everyday news, words of support, and reminders of home. Avoid sending bad news unless it truly matters, and ask the recruiter before mailing anything other than letters.
- Know the emergency process. For true family emergencies, the American Red Cross Emergency Communication Services is the official way to reach a recruit.
- Use the recruiter as your contact. Your recruit’s local recruiter is the best person to answer questions during training.
- Plan for graduation early. Check the official depot website for graduation details and make travel plans well in advance.
Preparing Together
Boot camp is something your recruit has to do on their own, but the preparation does not have to be. The months of DEP are a chance to train together, talk about what is coming, and build the confidence they will lean on when things get hard. When they walk across the parade deck as Marines, the work you did together before ship day will be part of that moment.
Frequently Asked Questions
What are the Initial Strength Test standards for Marine Corps boot camp?
Males must do 3 pull-ups or 34 push-ups in 2 minutes, hold a 40-second plank, and run 1.5 miles in 13:30 or less. Females must do 1 pull-up or 15 push-ups in 2 minutes, hold a 40-second plank, and run 1.5 miles in 15:00 or less. Confirm current standards with your recruiter.
How long is Marine Corps boot camp?
Recruit training lasts 13 weeks and is divided into four phases: Foundation, Immersion, Transformation, and Transition. Receiving and graduation week are part of the overall experience.
Can I call or text my recruit during boot camp?
No. Recruits make one short call when they arrive, and after that communication is by letters and postcards. Recruits get limited phone and internet access during specific periods after the Crucible.
How is it decided whether a recruit goes to Parris Island or San Diego?
It is generally based on where the recruit enlists. Recruits from west of the Mississippi River usually go to San Diego, and those from the east usually go to Parris Island. Both depots now train male and female recruits.
What should my recruit bring to boot camp?
Very little. A valid photo ID, a Social Security card, any documents the recruiter requests, and a written list of addresses are the essentials. The recruiter’s official packing list is the final word.
When can families see their recruit again?
Family Day, held the day before graduation, is usually the first chance to visit in person. Graduation details are posted on each recruit depot’s official website.
