Your Soldier just left for Fort Jackson and the 10 weeks ahead can feel like a black box. Here's what's actually happening, phase by phase, so you know roughly where they are in training even if you can't talk often.
The Short Version
- Week 0 — Zero Week (Reception): paperwork, medical exams, gear issue, battalion assignment.
- Weeks 1–3 — Red Phase: foundational skills, mostly classroom and drill.
- Weeks 4–5 — White Phase: rifle marksmanship and qualification.
- Weeks 6–9 — Blue Phase: advanced combat tasks, field training.
- Week 10: final field training, Family Day, and graduation.
Every cycle and battalion can vary slightly in timing. This is the typical structure.
Week 0: Zero Week (Reception)
Before training officially starts, new trainees go through Reception — usually with the 120th Adjutant General Battalion. This is all administrative: medical and dental screening, initial uniform and equipment issue, setting up military pay, and getting assigned to a company, platoon, and one of Fort Jackson's training battalions. Your Soldier may only get brief phone access during this stretch, often just enough for a quick "I made it" call.
Weeks 1–3: Red Phase
This is where Basic officially begins, and it's the toughest adjustment period. Trainees meet their drill sergeants for the first time and start building the foundation: rifle marksmanship fundamentals, personal financial management, the Law of Land Warfare, land navigation with a map and compass, physical readiness and nutrition, rappelling, drill and ceremony, and basic fieldcraft. Most classroom-style instruction happens during this phase. Families often describe this as the quietest stretch for communication — expect fewer letters and calls while your Soldier adjusts.
Weeks 4–5: White Phase
Sometimes called the rifleman or qualification phase. Training shifts almost entirely to marksmanship: zeroing a rifle, engaging targets at different distances and positions (prone supported, prone unsupported, kneeling), and eventually qualifying under time pressure with multiple targets. Rifle qualification is a major training requirement, so this phase carries real weight for your Soldier.
Weeks 6–9: Blue Phase
By now your Soldier is combining everything they've learned into more advanced tasks: close combat and optics, squad-level patrolling and attacks, crew-served weapons like the M240B machine gun and AT4 rocket launcher, urban operations (MOUT), convoy defense, IED awareness, and long-distance road marches carrying a combat load. This is also when extended field exercises happen, including nights sleeping outdoors on Fort Jackson's training ranges.
Week 10: Field Training, Family Day & Graduation
The final week starts with the culminating field training event and a long road march in full gear, often covering around 15 kilometers. Once that's done, your Soldier gets Family Day — see our Family Day guide for what that day actually looks like — followed by the formal graduation ceremony on Hilton Field the next morning. See the full graduation schedule for ceremony times. The day after graduation, new Soldiers typically head to Advanced Individual Training (AIT) to learn their specific job in the Army.
How to Stay Connected During Training
Phone and internet access is limited and controlled entirely by your Soldier's drill sergeants — it is not something you can schedule from your end. The one reliable channel the whole way through is mail. See our guide on how to mail your Soldier at Fort Jackson for the address format and what you can and can't send.

Frequently Asked Questions
How long is Basic Combat Training at Fort Jackson?
Basic Combat Training takes 10 weeks, following Zero Week (Reception), where trainees complete medical exams, paperwork, pay setup, and get assigned to a company, platoon, and battalion.
