There's a distinction between "deployed to Joint Base Bunga Bunga to support combat operations in Grungistan" and "deployed to a 5000-person airbase that's been active for 62 years".
So these cases are the same? You can call it semantics, but there's a difference between going to Iwakuni (or Lakenheath. for that matter) on a long-planned operation, and being able to answer the phone for a Cocom needing support. There always is one, and it's normal. It's the difference between IOC and FOC.
