Fort Sam Houston vs Joint Base Lewis-McChord
Army, TX vs Army, WA
Fort Sam Houston: "Where Every 68-Series Goes to Get Medically Confused." Joint Base Lewis-McChord: "The One Base Everyone Wants (Until the Mold Sets In)." Same base pay, same TRICARE, two entirely different answers to "would you go back?"
Honest version: Fort Sam Houston — Army Medical Center of Excellence, San Antonio is affordable and fun, but Brutal summer heat. Joint Base Lewis-McChord — I Corps, Pacific Northwest outdoor recreation, but Rain nearly every day Oct-May. You'll spend more of your actual life in San Antonio, TX or Tacoma, WA than on any range. That's worth weighing. Fort Sam Houston keeps your finances stable. Joint Base Lewis-McChord keeps them "interesting" — and in military finance, "interesting" is never a compliment. Weather: Fort Sam Houston serves Hot summers, mild winters, low humidity for Texas. Joint Base Lewis-McChord counters with Mild year-round, rainy 8 months, gorgeous summers. Your uniform was designed for approximately neither.
Two Army posts that produce a very specific type of person who will never stop talking about where they were stationed.

The Read
What nobody bothers to tell you until you arrive.
JBLM is the closest the Army has to a Pacific power-projection platform on the mainland, and that shapes the assignment more than any of the brochure photos let on. I Corps is the senior headquarters and the four-star INDOPACOM-aligned operational command; 7th Infantry Division provides the conventional combat structure; 1st Special Forces Group is here (with regular deployments westbound across the Indo-Pacific); 75th Ranger Regiment's 2nd Battalion is at JBLM-Lewis. The 62nd Airlift Wing flies C-17s out of McChord and a meaningful chunk of any Pacific deployment goes through this dual-runway joint installation. INDOPACOM tempo is increasing across the entire DoD posture and JBLM is downstream of that — exercises, KASS rotations, JPMRC-X cycles, and PACAF interoperability sets put a lot of units on the road. Madigan Army Medical Center is one of the better Army MTFs and rarely forces off-post specialty referrals. The honest trade-off is cost of living: Tacoma, Lacey, and DuPont rents have surged with the Puget Sound housing market — BAH for an E-5 with deps under MHA WA311 is $2,556 (one of the highest in the conventional Army), but 3BR rents in DuPont and Steilacoom run $2,000-$2,800 routinely, and Tacoma proper goes higher. Washington has no state income tax which materially helps. Schools at Steilacoom Historical SD and North Thurston Public are well-regarded; on-post DoDEA elementaries (K-8) are strong. The weather is the local cliché: 8 months of overcast/drizzle Oct-May, then world-class July-September. The PNW outdoor-recreation lifestyle is real — Mount Rainier is in the backyard, Olympic National Park is two hours, and Crystal Mountain skiing is a day trip.

Real Talk
What you’ll actually deal with. The structured table above is the brief — this is the back-channel.
Liberty Military Housing (formerly Lincoln) manages on-post — JBLM-Lewis Main and McChord housing areas; waitlists are real (3-6 months for family housing) but the stock has been refreshed over the last decade and is generally good. Off-post: DuPont is the closest, walkable to McChord side, premium-priced. Lakewood is closer/cheaper and uneven (vary by neighborhood — Tillicum struggles, Lake City is solid). Steilacoom is the small-town move with the best schools and water views, premium-priced. Lacey/Olympia (15-20 min south on I-5, off the worst of the Tacoma traffic) is the budget-conscious family move with good North Thurston schools.
Steilacoom Historical SD and Clover Park SD serve the immediate JBLM area — Steilacoom is the strong feeder, Clover Park is uneven. DoDEA operates on-post K-8 schools (Beachwood, Carter Lake, Clarkmoor, Evergreen, Greenwood, Hillside) — well-regarded for continuity through PCS/deployment cycles, no DoDEA high school. North Thurston Public Schools (Lacey) is the south-of-post move with strong districts (River Ridge, Timberline).
I Corps OPTEMPO is rising with INDOPACOM posture. 7th ID brigades rotate through JPMRC-X (Hawaii/Alaska Pacific Multinational Readiness Center) and CTC events. 1st SFG and Ranger 2nd Bn run their own SOF tempo. McChord airlift crews are deployed continuously supporting global airlift. Garrison-side (I Corps staff, Madigan) runs civilian-leaning hours and is calmer.
An assignment where the lifestyle (PNW outdoors + no state income tax + a real MTF) and the mission (Pacific power projection) both punch above their reputation. Cost of living is the structural tax — going in eyes-open on rent is the difference between a great tour and a strained one.
Who Thrives Here
Not every base is for every service member. Match yourself to the room.
- INDOPACOM-FOCUSED CAREERISTS
I Corps is the four-star Pacific HQ. 1st SFG, 7th ID, and 75th Ranger Regt 2nd Bn all align to Pacific theater commitments. Career signal for INDOPACOM-track assignments is strong.
- PNW OUTDOOR FAMILIES
Rainier, Olympic NP, Cascades skiing, Puget Sound kayaking and sailing, Pacific coast beaches — the outdoor recreation density is unmatched in CONUS Army.
- DUAL-INCOME TECH SPOUSES
Amazon, Microsoft, Boeing, and a deep PNW tech corridor are within Seattle-area commuting distance. Remote-work culture is mature. Spouse careers in tech, healthcare, and logistics translate well.
- NO-TAX-STATE BANKERS (WA SLR)
Washington has zero state income tax. With BAH among the highest in the conventional Army, WA SLR pulls real money to the bottom line for career SMs.
