Training at Fort Sill
The three phases at Fort Sill, verified against the garrison training schedule:
- 10 weeks, three phases. Red Phase → White Phase → Blue Phase, with a culminating field exercise before graduation.
- One phone call at arrival. Your Soldier calls when they reach the reception battalion to give you their mailing address. After that, letters are the main channel through Red Phase.
- Silence near the end is normal. The final field exercise cuts off phone contact for several days. It means things are going well.
- AIT is elsewhere for most grads. After BCT graduation, your Soldier ships to their MOS school at a different installation. Some posts run OSUT, where BCT and AIT are combined. Confirm your Soldier’s training track.
The phases
Red Phase
Weeks 1-3Reception and Total Control. Drill and ceremony, Army values and history, weapon familiarization, basic first aid and Combat Life Saver introduction, land navigation fundamentals, the gas chamber, pugil sticks, and a sharp ramp in physical conditioning. The same Red Phase that runs at every Army BCT installation.
White Phase
Weeks 4-6Marksmanship: zero and qualification on the M-16/M-4, plus advanced land navigation, longer rucks, fieldcraft, tactical movements, and Combatives progression. Standard Army White Phase content; Fort Sill-specific Field Artillery instruction comes in AIT after BCT, not during these phases.
Blue Phase
Weeks 7-10, The ForgeAdvanced field training culminating in The Forge: a four-day FTX covering ~40+ miles of road march, patrol base operations 80+ hours, a night infiltration course, combat obstacles, and roughly four hours of sleep per night. Concludes with a Rite of Passage where trainees don the black beret for the first time. Sill color: a Warrior Meal (all-you-can-eat buffet served by drill sergeants) and a morale event with trainee impressions of their cadre.
Staying in touch during training
What to expect each phase. Confirm the specifics with your Soldier’s unit since drill sergeant discretion varies by company.
| Phase | Phone calls | Letters |
|---|---|---|
| Red Phasewks 1–3 | One call on arrival to give you their address; phone collected after that. Sunday calls at drill sergeant’s discretion. | Best channel. Write often; address confirmed on that arrival call. |
| White Phasewks 4–6 | Sunday calls more consistent as the platoon earns the privilege; length and frequency at drill sergeant’s discretion. | Still arrives in batches; may slow during intensive field or range weeks. |
| Blue Phasewks 7–10 | Contact before The Forge; none during the FTX (in the field, no phones). | Irregular; field time increases in this phase. |
The table above reflects the Army-wide BCT pattern. Specific call frequency, length, and Sunday-call policies vary by company and drill sergeant. Confirm with your Soldier’s unit. Silence for several days near the end of training (The Forge) is expected and means things are going well.
One call at arrival
Your Soldier calls when they reach reception to give you their mailing address. After that, the phone is collected. Write the address down immediately.
Letters are the reliable channel
Across all BCT phases, letters are the most consistent way to reach your Soldier. They arrive in batches. Keep writing even if responses slow during heavy field weeks.
Silence before graduation is normal
When The Forge starts, phone contact stops. Several days of silence means your Soldier is in the field. It is a good sign, not a bad one.

Common questions
- What is Army BCT graduation week?
- Army BCT graduation week is the final stretch of Basic Combat Training when family members are invited on post to observe ceremonies and spend time with their Soldier. The arc is typically: Family Day (the day before graduation, when family can visit and the Soldier may be released for a few hours) followed by Graduation Day (the formal ceremony and release). The exact schedule varies by installation. Some bases hold a separate Turning Blue or coin ceremony; others fold everything into a single parade.
- When does my Soldier ship to AIT after BCT graduation?
- Most BCT graduates ship to Advanced Individual Training (AIT) within 24-72 hours of graduation. The exact timing depends on whether AIT is at the same post or requires a flight: at Fort Sill (Field Artillery + Air Defense Artillery), most grads transition into on-post AIT the same week; at Fort Jackson, most ship out to another post for AIT (Adjutant General, Quartermaster, Signal, etc.). Your Soldier's ship-out time is on their orders and is non-negotiable. Plan flights and the family pass window around it. Some Soldiers will fly out the night of graduation; others bus to a new post the next morning.
- When is AIT graduation at Fort Sill?
- There is no single published AIT graduation schedule at Fort Sill. Most Fort Sill BCT graduates transition directly into Advanced Individual Training (AIT) on the same post, since the Field Artillery (FA) and Air Defense Artillery (ADA) MOS schools are both located here. But AIT course length varies by MOS, so AIT graduates on a different, unit-specific timeline than BCT, not a fixed calendar this site can publish. The BCT graduation ceremony (the dates and schedule on this page) is the trip most families travel for. Some families extend their visit or plan a second trip for AIT completion, but the 434th Field Artillery Brigade advises that travel for AIT is generally not authorized, so confirm with your Soldier's AIT unit directly before booking anything. Your Soldier's unit, not a public garrison calendar, is the source for AIT ceremony details.
