DUTY STATION COMPARISON
Fleet Activities Yokosuka vs Fort Buchanan
Navy vs Army, PR
The Intel
Fleet Activities Yokosuka: "7th Fleet: Where Your Ship Is Always Deployed and the Vending Machines Have Beer." Fort Buchanan: "The Army Base That Accidentally Ended Up in Paradise." One installation was built for retention. The other was built to test resolve. Both succeed.
The whole-family version of this comparison: Both sit in that frustrating middle ground — not saving, not hemorrhaging, just existing in budget purgatory with a commissary discount. For spouses: SOFA limits off-base employment at Fleet Activities Yokosuka. At Fort Buchanan: Limited on-post. The off-post reality that defines day-to-day life: Yokosuka, Japan versus San Juan, PR. Everything else is logistics.
Different branches, different installations, same realization at end of tour: the duty station didn't define you — but it sure left fingerprints.
