The moment your recruit ships out, one question takes over everything: what happens now, and for how long? You've got a rough sense that Marine boot camp is longer than other branches, but "13 weeks" doesn't mean much until you know what's actually happening inside those weeks—and when you should expect to hear from your Marine, and when you shouldn't.
This is your map. Think of it as the "start here" page for the whole journey—every stage below links to a full guide if you want to go deeper once you get there.
Quick answer: Marine boot camp lasts 13 weeks — the longest recruit training of any U.S. military branch. It's made up of Recruit Receiving, three numbered training phases, and a final "Marine Week" that ends in Family Day and graduation. The training itself is identical whether your recruit is at Parris Island, South Carolina, or MCRD San Diego, California.
How Long Is Marine Boot Camp?
Marine Corps boot camp—officially called Recruit Training—runs 13 weeks, making it the longest basic training of any branch (compare that to roughly 7.5 weeks for the Air Force or 9 weeks for the Navy). It's also one of the only branches with no weekend leave and no ability to leave base at all until graduation.
Where your recruit trains depends on where they're from, not on anything you can choose:
- MCRD Parris Island, South Carolina—recruits from east of the Mississippi River, and all female recruits.
- MCRD San Diego, California—male recruits from west of the Mississippi River.
Both depots run the exact same 13-week training pipeline. The only real differences are geography, climate, and a few site-specific landmarks—the schedule itself doesn't change based on where your recruit ends up.
The Phases of Marine Boot Camp, Week by Week
Marine boot camp is broken into Recruit Receiving, three numbered training phases, and a final graduation stretch. Here's what each one means for your recruit—and for you.
Recruit Receiving (the first few days)
Before training officially starts, your recruit spends their first few days in "Receiving"—in-processing, their first haircut, medical and dental screening, uniform and gear issue, and the Initial Strength Test to confirm they're ready to begin. The first Friday at the depot is nicknamed "Black "Friday"—the day recruits officially meet the drill instructors who'll be with them for the rest of the training.
For you: this is when you'll get the one phone call every recruit is allowed during receiving—short, scripted, and mostly just confirming they arrived safely. After that call, expect silence until your first letter arrives.
Phase 1 — Weeks 1 to 3: Building the Foundation
This is where the culture shock everyone talks about actually happens. Recruits are stripped of civilian habits—down to how they refer to themselves ("this recruit," not "I")—and start learning close-order drill, weapons safety, first aid, Marine Corps history, and the basics of the Marine Corps Martial Arts Program (MCMAP).
For you: this is when letters start flowing regularly, and it's the best window to send mail and a first care package. If you haven't already, this guide to sending a care package during Marine boot camp covers exactly what to send and when.
Phase 2 — Weeks 4 to 7: The Longest Stretch
Phase 2 is the longest of the three, and it's where the physical demands really ramp up. This is Swim Week (water survival and drown-proofing), Team Week (a short break from constant training to help with base upkeep—and when recruits get their Dress Blues photos taken), and steadily increasing physical testing.
For you: this is the steady middle of the journey—the phase with the least drama and the most routine mail. It's a good stretch to lean on other Marine moms for company while the days blur together.
Phase 3 — Weeks 8 to 11: Marksmanship, Field Skills, and the Crucible
Phase 3 shifts focus to rifle marksmanship qualification, fieldcraft, and combat skills—everything builds toward the defining event of boot camp: the Crucible, a 54-hour final test near week 10 that ends with recruits earning their Eagle, Globe, and Anchor and being addressed as "Marine" for the first time.
For you: this phase includes the hardest stretch of silence in the entire 13 weeks. If you're heading into this phase now, our Marine mom's survival guide to the Crucible walks through exactly what to expect and how to get through the 54 hours of no contact.
Marine Week & Graduation — Weeks 12 to 13
The final stretch is often called Marine Week—final administrative tasks, last physical testing, and preparation for graduation. This is when Family Day and the official graduation ceremony happen, and when you'll finally see your Marine in person.
For you: this is the part you've been counting down to from day one. Our Marine Corps boot camp graduation and Family Day guide covers travel, what to expect at each event, and how the weekend is structured.
What Happens After Graduation?
Graduation isn't quite the end of the road. Your Marine gets about 10 days of leave, then reports to the School of Infantry, followed by MOS school to learn their specific job, before finally receiving orders to their first duty station. If you're not sure what that stretch looks like, our guide to what happens after Marine boot camp graduation walks through it step by step.

Staying Connected Through Every Phase
Thirteen weeks is a long time to sit with uncertainty, and the rhythm of this journey—steady mail, then total silence, then celebration—is a lot for any mom to carry alone. Every phase above has its own emotional weight, and it helps to have both a community and a way to mark the moments that matter.
For the community side, our guide to Marine mom support groups and resources rounds up both official programs and peer-led groups worth joining before you need them, not after.
And for the moments worth marking—the day they leave, the day you get through the Crucible silence, the day you finally see them at graduation—our Marine Mom collection is built around exactly that kind of pride, from day one through every phase after.
FAQ: Marine Boot Camp Length & Schedule
How long is Marine Corps boot camp? 13 weeks total—the longest of any U.S. military branch.
What are the phases of Marine boot camp called? Recruit Receiving, followed by Phase 1, Phase 2, and Phase 3, then a final graduation stretch sometimes called Marine Week.
Which week is the hardest? Most Marine moms and recruits point to Phase 3, specifically the Crucible around week 10—both for the physical demands on the recruit and the total communication blackout for family.
How often will I hear from my recruit? After the single phone call during Receiving, communication is mail-only until graduation, with the exception of the 54-hour blackout during the Crucible. Letters tend to flow most steadily during Phases 1 and 2.
Is training different at Parris Island vs. San Diego? No—both depots follow the same 13-week, three-phase training pipeline. The differences are geographic, not structural.
What happens right after graduation? Your Marine gets about 10 days of leave, then moves on to the School of Infantry, a MOS school, and eventually a first duty station assignment.
Not sure which stage your recruit is in right now? Start with sending a care package, get ready for the Crucible, plan for Family Day and graduation, or look ahead to what comes after boot camp.
